It will cause the dwarf to flash with a downward red arrow, and {{DFtext|Over the long term, Urist McStressed has been under a great deal of stress.|6:1}} will show on their [[thoughts and preferences]] tab. | ||

In the short term, excessive levels of stress will lead to temporary '''emotional breakdowns''' – throwing [[tantrum]]s, slipping into [[depression]], or stumbling around [[oblivious]]ly. If they're under stress for prolonged periods of time, dwarves will become Harrowed, their thoughts and preferences tab reading: {{DFtext|Urist McStressed has been utterly harrowed by the nightmare that is his tragic life.|5:1}} If this persists for long enough, it will lead to '''[[insanity]]'''. |
| − | Animals can also be stressed, which seems to happen when an animal has been constrained for a long time. | + | Animals can also be stressed, which seems to happen when an animal has been constrained for a long time. Internally, stress level is tracked with one number, where a negative number is good and a positive number is bad – it is not possible to view this number without third-party [[utilities]]. Stress ranges from -1000000 to +1000000, and the negative effects start appearing at +10000, +25000, and +50000. Stress itself gradually increases or decreases based on thoughts incurred. |
| − | + | == Detailed mechanics == | |
| + | === How stress works === | ||
| + | First, to bust a myth: [[discipline]] is not an indicator of how well a dwarf copes with stressful situations, but there is a correlation that will be explained below. | ||
| − | + | When a dwarf experiences an emotion, whether from an immediate experience or from revisiting a long-term memory, a certain number of points, which will be called "stress points", are added to that dwarf's "stress score". The dwarf keeps a running tally of their stress points, determining their mood. Unhappy thoughts add to the stress score, happy thoughts subtract from the stress score. It is confirmed that there are only two things that affect stress: the emotions that a dwarf experiences, each of which is shown on the thoughts and preferences screen, and a return towards a neutral point over time. | |
| − | + | There are three key personality traits which determine a dwarf's propensity to experience stress: bravery, which determines how fast a dwarf accumulates stress; stress vulnerability, which determines how much stress a dwarf can experience before breaking [note 4]; and anxiety, which determines how fast a dwarf dissipates stress. A fourth trait, depression propensity, seems to be related to the difficulty of recovering an unhappy dwarf, but requires additional testing. | |
| + | |||
| + | There are some experiences which have a constant and predictable effect across all dwarves and others that are much more variable. In assessing the impact of an experience on a dwarf's stress score, a key measure is whether or not the resulting emotion was promoted to a dwarf's long term memory, as these tend to be the stronger emotions and are those that are revisited. | ||
| + | |||
| + | The results below are taken from a sample of 300 dwarves across 3 fortresses, where all dwarves had been in their fortress for more than 2 years. The fortresses were designed to "molly-coddle" the dwarves, shielding them as much as possible from rain, death, corpses and miasma, and promoting happy thoughts as much as possible (after year 2, because it took 2 years and 5 migrant waves to reach that point with the infrastructure). The fortresses each had 150+ dwarves and had been run for 7 years. The overall mood of the fortresses after 7 years was 45% happy to ecstatic, 55% fine, less than 1% unhappy (4 dwarves in total). | ||
| + | |||
| + | === Stress reducers === | ||
| + | ==== Bedrooms ==== | ||
| + | More than 99% of dwarves had short-term memories of feeling blissful sleeping in a bedroom like a personal palace, 89% were also experiencing long-term memories of remembering feeling blissful about their bedroom. This was achieved by giving them a 3x3 engraved bedroom. | ||
| + | |||
| + | ==== Dining room ==== | ||
| + | 88% of dwarves had short-term memories of feeling blissful eating in a legendary dining room, 70% were also experiencing long term memories of remembering feeling blissful about their dining room. This was achieved by digging out a 15 x 20 room and designating it as a dining room; it doesn't take much to impress them in this regard, but to force them to eat there, you have to restrict placing unallocated tables anywhere else in the fortress. | ||
| + | |||
| + | ==== Meaningful work ==== | ||
| + | 93% of dwarves were satisfied at work, 62% had long term memories of being satisfied at work. Curiously, a number of dwarves had two memories of being satisfied at work. Satisfaction is a low-strength emotion, so it is suspected that this is the result of a long-term memory being overwritten by a stronger short-term memory of a different group, then cycling back in again because it was a frequent experience always ready to be promoted back from short-term memory. From what was seen, hauling is not a satisfying job, but any job which enables a skill increase can be satisfying work, so long as it doesn't conflict with a dwarf's personality (for example, a butcher will get unhappy thoughts if they have a deep respect for nature). | ||
| + | |||
| + | ==== Military training ==== | ||
| + | Military training is HUGE. After year 2 in each fortress, all dwarves were put into squads (no armor, no weapons), with each squad scheduled for one or two months of military training per year. 93% of dwarves had happy long-term memories of something relating to their military training, with 34% having more than one positive long-term memory. Gratitude or pleasure from sparring was the most common, with interest in improving a military skill (wrestling, dodging, biting, kicking, etc.) and pride in teaching a military skill also widely present. Additionally several dwarves were satisfied remembering improving discipline and/or observation. The effect of military training in clogging long-term memory with happy thoughts correlates with an increase in discipline, which is a common association between high-discipline dwarves suffering from low stress. No dwarves had negative long-term memories, despite some not liking warfare or not respecting military skills. A fairly reliable method to turn around unhappy dwarves using military training was noted, which will be discussed further below. | ||
| + | |||
| + | ==== Other things ==== | ||
| + | All dwarves had access to masterwork clothing, walked past an indoor [[waterfall]] frequently, were able to acquire an item, read books, and walked past fine furniture frequently, but less than 25% of dwarves retained their thoughts about these things in long-term memory. Spending time with family and pets will do quite a lot to help reduce a dwarf's stress. | ||
| + | |||
| + | === Stress increasers === | ||
| + | The median number of unhappy long-term memories across the sample of dwarves was only 1; most of the things that they were unhappy about in the long-term were things that would eventually be promoted to core memory: death, miasma, trauma, etc. Their other stress increasers were less than 1% of dwarves: being annoyed or irritated remembering being accosted by vermin; 1 dwarf was uneasy remembering becoming a parent; 1 dwarf was annoyed remembering drinking without a mug, which is suspected to have been a lingering long-term memory clogging their thoughts for several years; another was worried dwelling on not being able to help somebody and another was frustrated remembering the lack of traditions. | ||
| + | |||
| + | === Mixed and/or variable effects on stress === | ||
| + | ==== Praying ==== | ||
| + | 77% had long-term memories of wonder or enrapture from praying, 10% had negative long-term memories from being unable to pray, some dwarves had both positive and negative long term memories about praying. All dwarves had multiple positive and negative short-term thoughts about praying and not being able to pray. The balance of positive to negative long-term memories shows the effect of dwarves being unable to hold more than one thought of the same group in their short-term memory. As long as they get to pray more than once a year, they'll have a strong positive short-term memory about a deity and won't have room in their short-term memory to retain the negative thoughts from not being able to pray to the multiple gods that they wanted to. | ||
| + | |||
| + | ==== Performances ==== | ||
| + | All dwarves had multiple short-term memories about watching a performance or performing. However, a minority of thoughts were negative (about 5% were bored or embarrassed). Only a few dwarves had long-term memories related to performances/performing, all of them positive. | ||
| + | |||
| + | ==== Arguments ==== | ||
| + | Short-term memories about being upset getting into an argument were ubiquitous, and most dwarves had multiple short-term memories about arguing. However, only 3 dwarves were angry remembering getting into an argument (although 1 dwarf was exhilarated remembering this). | ||
| + | |||
| + | === Things that didn't matter === | ||
| + | Some things were ubiquitous in dwarves' short-term memories, but didn't appear at all in long-term memories. These are often the things that worry players seemingly more than the dwarves themselves. These were: being away from family; being away from friends; being sad at being separated from a loved one; not having decent meals; being unable to craft an item; and being unable to wander. | ||
| + | |||
| + | === Recovering unhappy dwarves === | ||
| + | From time to time, some dwarves would get stressed. In one test, an accident with a "malfunctioning" atom smasher occurred, which rained rotten body parts and gore all over the farmers. A dwarf in a strange mood was accidentally made to go berserk after the misapplication of a burrow command, several dwarves and their pets died of old age – usually in the middle of high-traffic corridors, and there were the usual unavoidable mishaps with visitors turning werebeast, trying to stage a coup, etc. Typically, around 10% of dwarves registered positive stress scores, with around 3% being so unhappy that they would be actively made to recover. | ||
| + | |||
| + | The first approach to trying to recover the stressed-out dwarves was to give them special attention and try to satisfy any unmet [[need]]s, in an attempt to overwrite some low-strength unhappy memories with happy memories. This had mixed results, was slow and took a lot of micromanagement. It would typically take about 2 years to turn around a mildly stressed dwarf. | ||
| + | |||
| + | During testing, a far more reliable and quick method to turn around stressed-out dwarves was found, using military training, in the form of a special "Therapy" military squad which was assigned to train all year round, and the squad was set to active/training on the squad menu. However, the squad was not assigned any barracks to train in. Any dwarf that was getting a bit down about things would be put into the Therapy Squad for a while. When a dwarf is scheduled to train, but has nowhere to train, they will actively seek to satisfy any needs. Rather than hang around with the "no job" label, they'll dash off to the tavern to socialise, the library to learn, the temple to pray or guildhall to increase their skills. It is far more effective, and easier to manage, than removing all of their tasks and hoping that they'll do something to cheer themselves up. It seems that they replace their duty to train with a duty to fulfill their needs. | ||
| + | |||
| + | After deploying this method and expanding it so that all dwarves got one month a year in which they were scheduled to train, but had no barracks, positive stress scores dropped to around 5%, with only 1 dwarf ever reaching the point of being unhappy (that particular dwarf being subjected to quite a lot of cycling up and down the stress levels to see what happened). | ||
| + | |||
| + | Of the 4 dwarves that became unhappy enough to be seemingly unrecoverable (3 from before the Therapy Squad method was discovered), all 4 dwarves had a depression propensity stat that was extremely low, meaning that they "were often sad and dejected". There were other dwarves in the fortresses with extreme depression propensities that didn't become unhappy, so it is unknown if this was a coincidence or whether it's just hard to turn around these dwarves once they reach an unhappy state. | ||
| + | |||
| + | === Combat hardness and immunity to corpses/stress === | ||
| + | There is a very old piece of code which measures the "[[Combat hardening|combat hardness]] value" of a dwarf. This value is listed as "detachment" in [[Utilities#Dwarf_Therapist|Dwarf Therapist]], although it doesn't appear in the default grid views. Toady said that when a dwarf sees guts and stuff, including seeing people die, it increases their combat hardness, which will eventually lead them to become immune to seeing corpses. This code predates the current stress system and is still active. Anecdotal reports of dwarves becoming immune to seeing corpses due to constant combat exist, which is why it was brought to question. It was attempted to bring some dwarves to the maximum state of "doesn't really care about anything anymore", but after 10 years of running a fortress with one squad dedicated to fighting goblins released from cages, only the intermediate level of "is a hardened individual" was reached. There was fighting indoors, so it required frequent breaks to remove corpses to prevent miasma. There was an attempt at discovering which aspects of the stress system would be overridden by combat hardness – which things would a dwarf become immune to? Would it be everything? Do they not feel happiness or unhappiness about anything anymore? Can a dwarf still go berserk? Trying to test that concurrently with the rest of the experiment didn't sit well alongside the molly-coddle approach, so it was not pursued further, but knowing the effect on all aspects of stress would be interesting.{{verify}} | ||
| + | |||
| + | Anecdotal evidence [http://www.bay12forums.com/smf/index.php?topic=177991.0] from version 0.47.05 seems to indicate that dwarves gain combat hardness much more quickly than they did in previous versions. Even without taking any special measures, it seems common for most of the adult population to have some level of combat hardness, and it's not unusual for civilians who have never been in combat to reach the highest level of "doesn't really care about anything anymore". | ||
| + | |||
| + | === Conclusion === | ||
| + | To keep stress down, keep the things that end up in core memory to a minimum, or at least restrict the variety of strong unhappy memory groups that dwarves are exposed to in any particular year – in particular, seeing corpses, sentient things die, being exposed to miasma and rain and vomiting because of the sun. If you plan on fighting rather than turtling, plan to battle underground so that the dwarves aren't exposed to sun and rain at the same time as death and corpses. If a dwarf sees a corpse, get them hauling all of the corpses, as they'll only remember the first one. If they're exposed to rain, get them to do all of the outdoor work quickly and keep the rest of the dwarves dry. If you have to pick somebody to do unsavory work, choose the dwarf(s) with the best mix of bravery, stress vulnerability and anxiety. | ||
| + | |||
| + | Clog a dwarf's long-term memory slots with happy thoughts that can't be promoted. Give them a big room to dine in very early on; even if they only have one table and chair to eat on, it'll still count, but get them enough chairs and tables as soon as possible. Give them a wide variety of things to have happy thoughts about, as multiple low-strength short-term memories have a chance at cycling out low-strength unhappy memories and preventing them from sticking. Put everybody in a military squad as soon as you can afford the labor – don't worry about weapons and armor; just get them training in any old dirt hole of a barracks for at least one month of the year (you might want to make sure that your mayor and trader are training over winter when there are no caravans or delegations). As soon as you can give everybody a 3x3 engraved bedroom, that's a sure-fire mood enhancer. Make sure that you have at least one temple and that the dwarves have a bit of downtime to pray. | ||

[ANXIETY_PROPENSITY] affects the rate at which dwarves dissipate stress. For example, being out in the sun seems to affect dwarves quite strongly in terms of stress. |

Stress is a condition that is similar to unhappiness in earlier versions. It will cause the dwarf to flash with a downward red arrow, and Over the long term, Urist McStressed has been under a great deal of stress. will show on their thoughts and preferences tab.
Dwarves under stress for long periods of time will develop worse symptoms of stress, e.g: Urist McStressed has become haggard and drawn due to the tremendous stresses placed on him.. In the short term, excessive levels of stress will lead to temporary emotional breakdowns – throwing tantrums, slipping into depression, or stumbling around obliviously. If they're under stress for prolonged periods of time, dwarves will become Harrowed, their thoughts and preferences tab reading: Urist McStressed has been utterly harrowed by the nightmare that is his tragic life. If this persists for long enough, it will lead to insanity.
Animals can also be stressed, which seems to happen when an animal has been constrained for a long time. Internally, stress level is tracked with one number, where a negative number is good and a positive number is bad – it is not possible to view this number without third-party utilities. Stress ranges from -1000000 to +1000000, and the negative effects start appearing at +10000, +25000, and +50000. Stress itself gradually increases or decreases based on thoughts incurred.
Detailed mechanics[edit]
How stress works[edit]
First, to bust a myth: discipline is not an indicator of how well a dwarf copes with stressful situations, but there is a correlation that will be explained below.
When a dwarf experiences an emotion, whether from an immediate experience or from revisiting a long-term memory, a certain number of points, which will be called "stress points", are added to that dwarf's "stress score". The dwarf keeps a running tally of their stress points, determining their mood. Unhappy thoughts add to the stress score, happy thoughts subtract from the stress score. It is confirmed that there are only two things that affect stress: the emotions that a dwarf experiences, each of which is shown on the thoughts and preferences screen, and a return towards a neutral point over time.
There are three key personality traits which determine a dwarf's propensity to experience stress: bravery, which determines how fast a dwarf accumulates stress; stress vulnerability, which determines how much stress a dwarf can experience before breaking [note 4]; and anxiety, which determines how fast a dwarf dissipates stress. A fourth trait, depression propensity, seems to be related to the difficulty of recovering an unhappy dwarf, but requires additional testing.
There are some experiences which have a constant and predictable effect across all dwarves and others that are much more variable. In assessing the impact of an experience on a dwarf's stress score, a key measure is whether or not the resulting emotion was promoted to a dwarf's long term memory, as these tend to be the stronger emotions and are those that are revisited.
The results below are taken from a sample of 300 dwarves across 3 fortresses, where all dwarves had been in their fortress for more than 2 years. The fortresses were designed to "molly-coddle" the dwarves, shielding them as much as possible from rain, death, corpses and miasma, and promoting happy thoughts as much as possible (after year 2, because it took 2 years and 5 migrant waves to reach that point with the infrastructure). The fortresses each had 150+ dwarves and had been run for 7 years. The overall mood of the fortresses after 7 years was 45% happy to ecstatic, 55% fine, less than 1% unhappy (4 dwarves in total).
Stress reducers[edit]
Bedrooms[edit]
More than 99% of dwarves had short-term memories of feeling blissful sleeping in a bedroom like a personal palace, 89% were also experiencing long-term memories of remembering feeling blissful about their bedroom. This was achieved by giving them a 3x3 engraved bedroom.
Dining room[edit]
88% of dwarves had short-term memories of feeling blissful eating in a legendary dining room, 70% were also experiencing long term memories of remembering feeling blissful about their dining room. This was achieved by digging out a 15 x 20 room and designating it as a dining room; it doesn't take much to impress them in this regard, but to force them to eat there, you have to restrict placing unallocated tables anywhere else in the fortress.
Meaningful work[edit]
93% of dwarves were satisfied at work, 62% had long term memories of being satisfied at work. Curiously, a number of dwarves had two memories of being satisfied at work. Satisfaction is a low-strength emotion, so it is suspected that this is the result of a long-term memory being overwritten by a stronger short-term memory of a different group, then cycling back in again because it was a frequent experience always ready to be promoted back from short-term memory. From what was seen, hauling is not a satisfying job, but any job which enables a skill increase can be satisfying work, so long as it doesn't conflict with a dwarf's personality (for example, a butcher will get unhappy thoughts if they have a deep respect for nature).
Military training[edit]
Military training is HUGE. After year 2 in each fortress, all dwarves were put into squads (no armor, no weapons), with each squad scheduled for one or two months of military training per year. 93% of dwarves had happy long-term memories of something relating to their military training, with 34% having more than one positive long-term memory. Gratitude or pleasure from sparring was the most common, with interest in improving a military skill (wrestling, dodging, biting, kicking, etc.) and pride in teaching a military skill also widely present. Additionally several dwarves were satisfied remembering improving discipline and/or observation. The effect of military training in clogging long-term memory with happy thoughts correlates with an increase in discipline, which is a common association between high-discipline dwarves suffering from low stress. No dwarves had negative long-term memories, despite some not liking warfare or not respecting military skills. A fairly reliable method to turn around unhappy dwarves using military training was noted, which will be discussed further below.
Other things[edit]
All dwarves had access to masterwork clothing, walked past an indoor waterfall frequently, were able to acquire an item, read books, and walked past fine furniture frequently, but less than 25% of dwarves retained their thoughts about these things in long-term memory. Spending time with family and pets will do quite a lot to help reduce a dwarf's stress.
Stress increasers[edit]
The median number of unhappy long-term memories across the sample of dwarves was only 1; most of the things that they were unhappy about in the long-term were things that would eventually be promoted to core memory: death, miasma, trauma, etc. Their other stress increasers were less than 1% of dwarves: being annoyed or irritated remembering being accosted by vermin; 1 dwarf was uneasy remembering becoming a parent; 1 dwarf was annoyed remembering drinking without a mug, which is suspected to have been a lingering long-term memory clogging their thoughts for several years; another was worried dwelling on not being able to help somebody and another was frustrated remembering the lack of traditions.
Mixed and/or variable effects on stress[edit]
Praying[edit]
77% had long-term memories of wonder or enrapture from praying, 10% had negative long-term memories from being unable to pray, some dwarves had both positive and negative long term memories about praying. All dwarves had multiple positive and negative short-term thoughts about praying and not being able to pray. The balance of positive to negative long-term memories shows the effect of dwarves being unable to hold more than one thought of the same group in their short-term memory. As long as they get to pray more than once a year, they'll have a strong positive short-term memory about a deity and won't have room in their short-term memory to retain the negative thoughts from not being able to pray to the multiple gods that they wanted to.
Performances[edit]
All dwarves had multiple short-term memories about watching a performance or performing. However, a minority of thoughts were negative (about 5% were bored or embarrassed). Only a few dwarves had long-term memories related to performances/performing, all of them positive.
Arguments[edit]
Short-term memories about being upset getting into an argument were ubiquitous, and most dwarves had multiple short-term memories about arguing. However, only 3 dwarves were angry remembering getting into an argument (although 1 dwarf was exhilarated remembering this).
Things that didn't matter[edit]
Some things were ubiquitous in dwarves' short-term memories, but didn't appear at all in long-term memories. These are often the things that worry players seemingly more than the dwarves themselves. These were: being away from family; being away from friends; being sad at being separated from a loved one; not having decent meals; being unable to craft an item; and being unable to wander.
Recovering unhappy dwarves[edit]
From time to time, some dwarves would get stressed. In one test, an accident with a "malfunctioning" atom smasher occurred, which rained rotten body parts and gore all over the farmers. A dwarf in a strange mood was accidentally made to go berserk after the misapplication of a burrow command, several dwarves and their pets died of old age – usually in the middle of high-traffic corridors, and there were the usual unavoidable mishaps with visitors turning werebeast, trying to stage a coup, etc. Typically, around 10% of dwarves registered positive stress scores, with around 3% being so unhappy that they would be actively made to recover.
The first approach to trying to recover the stressed-out dwarves was to give them special attention and try to satisfy any unmet needs, in an attempt to overwrite some low-strength unhappy memories with happy memories. This had mixed results, was slow and took a lot of micromanagement. It would typically take about 2 years to turn around a mildly stressed dwarf.
During testing, a far more reliable and quick method to turn around stressed-out dwarves was found, using military training, in the form of a special "Therapy" military squad which was assigned to train all year round, and the squad was set to active/training on the squad menu. However, the squad was not assigned any barracks to train in. Any dwarf that was getting a bit down about things would be put into the Therapy Squad for a while. When a dwarf is scheduled to train, but has nowhere to train, they will actively seek to satisfy any needs. Rather than hang around with the "no job" label, they'll dash off to the tavern to socialise, the library to learn, the temple to pray or guildhall to increase their skills. It is far more effective, and easier to manage, than removing all of their tasks and hoping that they'll do something to cheer themselves up. It seems that they replace their duty to train with a duty to fulfill their needs.
After deploying this method and expanding it so that all dwarves got one month a year in which they were scheduled to train, but had no barracks, positive stress scores dropped to around 5%, with only 1 dwarf ever reaching the point of being unhappy (that particular dwarf being subjected to quite a lot of cycling up and down the stress levels to see what happened).
Of the 4 dwarves that became unhappy enough to be seemingly unrecoverable (3 from before the Therapy Squad method was discovered), all 4 dwarves had a depression propensity stat that was extremely low, meaning that they "were often sad and dejected". There were other dwarves in the fortresses with extreme depression propensities that didn't become unhappy, so it is unknown if this was a coincidence or whether it's just hard to turn around these dwarves once they reach an unhappy state.
Combat hardness and immunity to corpses/stress[edit]
There is a very old piece of code which measures the "combat hardness value" of a dwarf. This value is listed as "detachment" in Dwarf Therapist, although it doesn't appear in the default grid views. Toady said that when a dwarf sees guts and stuff, including seeing people die, it increases their combat hardness, which will eventually lead them to become immune to seeing corpses. This code predates the current stress system and is still active. Anecdotal reports of dwarves becoming immune to seeing corpses due to constant combat exist, which is why it was brought to question. It was attempted to bring some dwarves to the maximum state of "doesn't really care about anything anymore", but after 10 years of running a fortress with one squad dedicated to fighting goblins released from cages, only the intermediate level of "is a hardened individual" was reached. There was fighting indoors, so it required frequent breaks to remove corpses to prevent miasma. There was an attempt at discovering which aspects of the stress system would be overridden by combat hardness – which things would a dwarf become immune to? Would it be everything? Do they not feel happiness or unhappiness about anything anymore? Can a dwarf still go berserk? Trying to test that concurrently with the rest of the experiment didn't sit well alongside the molly-coddle approach, so it was not pursued further, but knowing the effect on all aspects of stress would be interesting.[Verify]
Anecdotal evidence [1] from version 0.47.05 seems to indicate that dwarves gain combat hardness much more quickly than they did in previous versions. Even without taking any special measures, it seems common for most of the adult population to have some level of combat hardness, and it's not unusual for civilians who have never been in combat to reach the highest level of "doesn't really care about anything anymore".
Conclusion[edit]
To keep stress down, keep the things that end up in core memory to a minimum, or at least restrict the variety of strong unhappy memory groups that dwarves are exposed to in any particular year – in particular, seeing corpses, sentient things die, being exposed to miasma and rain and vomiting because of the sun. If you plan on fighting rather than turtling, plan to battle underground so that the dwarves aren't exposed to sun and rain at the same time as death and corpses. If a dwarf sees a corpse, get them hauling all of the corpses, as they'll only remember the first one. If they're exposed to rain, get them to do all of the outdoor work quickly and keep the rest of the dwarves dry. If you have to pick somebody to do unsavory work, choose the dwarf(s) with the best mix of bravery, stress vulnerability and anxiety.
Clog a dwarf's long-term memory slots with happy thoughts that can't be promoted. Give them a big room to dine in very early on; even if they only have one table and chair to eat on, it'll still count, but get them enough chairs and tables as soon as possible. Give them a wide variety of things to have happy thoughts about, as multiple low-strength short-term memories have a chance at cycling out low-strength unhappy memories and preventing them from sticking. Put everybody in a military squad as soon as you can afford the labor – don't worry about weapons and armor; just get them training in any old dirt hole of a barracks for at least one month of the year (you might want to make sure that your mayor and trader are training over winter when there are no caravans or delegations). As soon as you can give everybody a 3x3 engraved bedroom, that's a sure-fire mood enhancer. Make sure that you have at least one temple and that the dwarves have a bit of downtime to pray.
Stress factors[edit]
Stress is affected by the emotions a dwarf experiences upon encountering certain circumstances; these encounters are temporarily shown as thoughts in the dwarf's profile, though the resulting stress can linger long after the thoughts are gone. The strength of the emotions (and the resulting stress values) vary based on the dwarf's personality. Controlled testing has shown that these sources of stress build up less in dwarves with high [BRAVERY] and low [STRESS_VULNERABILITY]. [ANXIETY_PROPENSITY] affects the rate at which dwarves dissipate stress. For example, being out in the sun seems to affect dwarves quite strongly in terms of stress.
Emotions and the level of stress or stress relief they cause are detailed in the table of emotions. Note that one event may cause different emotions for different dwarves (and, occasionally, for the same dwarf). The exact mechanisms of how it's decided what emotions are to follow are as of yet unclear, but there's a general consensus that it depends on both severity of factors and the personality of the dwarf in question.
Here is a partial table of emotions and what they can be caused by:
| Emotion | Cause |
|---|---|
| adoration | Giving birth to a baby, becoming a parent |
| admiration | Being next to completely sublime furniture, watching a performance |
| affection | Interacting with a pet, adopting a new pet, forming a bond with the trained animal, talking with a friend, making a new friend |
| aroused | Talking with the spouse, watching a performance |
| caring | Giving somebody food |
| empathy | Being yelled at/cried on by an unhappy citizen |
| enraptured | Communing with deity |
| fondness | Making a new friend, talking with a friend or a sibling, interacting with a pet |
| gratitude | Being rescued, receiving water or food, being granted residency, being elected as mayor, sparring |
| lustful | Talking with the spouse |
