Ramblings

Bravery denotes a person's willingness to accept risk.
It is primarily determined by an individual's perception of risk. Due to ignorance (or sometimes because of their protected status), children can tend to feel a bit too safe sometimes, whereas adults may tend to overestimate the stakes (especially of social situations) and become more defensive. Minor differences in braveness between people exist, major differences typically indicate a (perceived or actual) difference in wealth, safety, ability or another commodity that changes the stakes. Beware the crossover toward stupidity.

Being craven could be considered a social liability, but does tend to lead an individual towards very safe options, improving their longevity. Being very craven can become a major weakness, though being exceedingly brave does the same. People on opposite ends of this spectrum may tend to get into conflict.

The spectrum of calmness is tied to safety, maturity, bravery and intelligence, amongst others. Knowing more and understanding one's reality better leads to less frustration or worry. Wrath serves as a solution for those who cannot sufficiently rely on these resources.

Primarily an indication of sex drive. Not relevant and will rarely be used (it is also not upon me to judge such intimate details, with some very rare exceptions). Only part of this list as it is part of the traits from Crusader Kings 3, from which this list is heavily inspired.
Sex drive is largely environmental and depends on personal history. Age, career and illnesses play a major role as well.

Content people tend to have a steady source of self-worth, whereas ambitious people seek out at least part of their self-worth through continuous (self-)improvement. This can be pathologic, but is probably because the person just find great fulfilment in climbing ever higher.

Value seen in a particular piece of work. Since there are all different kinds of work we each value differently, it is very difficult to make a generalized statement about a person. Someone may be very lazy at school but extremely diligent in their basketball training, purely because of how much value a person sees in school as opposed to the basketball training.

Socially, performance at the workplace is generally seen as the primary indication for diligence/laziness. Personally, I try to strike a balance and consider all kinds of effort invested (or not) by the person.

Indication of how willing and how good a person is at letting go. Very important trait, as it defines the probable longevity of people getting along. While being too forgiving is harmful to oneself, it is very important to be able to forgive people for the things they do because of their (totally humane) weaknesses. Everyone has them, so a person without forgiveness would never be able to hold onto a person for very long.

Greed and generosity are probably learned survival strategies from early childhood to childhood. Greedy characters probably lived in an environment that forced them to be proactive, perhaps aggressive to fulfil their needs, whereas charitable characters were able to rely more on their environment to keep their needs decked and learned that being generous is socially advantageous.

Typically, greed ends up becoming less relevant as one ages, and there can be other factors at play that lead a character to “greedy” behavior, even if their environment doesn't force them to be greedy (anymore).

The scale of gregariousness describes the overall amount of social inhibition afflicting a character. Social inhibition varies naturally and everyone is inhibited to some degree. The resulting plot is one of the easiest bell curves imaginable.

Social inhibition can be learned or come about as part of other factors and/or individual temperament. Often largely environmental. Strong outliers tend to have psychological reasons for why that behavior is advantageous (ie. it is not natural).

Honesty and Deceit are learned survival strategies and depend strongly on the environment in which a character was raised. Deceitful characters can have learned it as a necessity to prevent them from showing vulnerability or manipulating the social environment to fulfil their needs. Honest characters probably grew up in an environment that rewarded such honesty.

Typically a measure of knowledge and experience, but extremely subjective trait strongly influenced by one's own knowledge and experience. Generally we are probably wrong, which arrogant people like to think they're not.

Hard to call someone arrogant without making yourself vulnerable. See Arrogance.

Everyone likes to think they're just, even if they admit to sometimes bend the rules to cater to their feelings. Or, nobody does things that they themselves consider egregiously unethical (ie. without a good reason). Therefore, this personality trait is largely based on my personal impression of either 1) what I consider Just or 2) whether a person sticks particularly staunchly to a moral system, even if I don't personally agree with it. The quintessential question here is whether a character believes in higher ideals, or if they just go with their gut.

Obviously, if those higher ideals are too questionable themselves then I will still have a hard time calling the person just.

Patience is a useful ability needed for interaction with other humans and perseverance through tasks. Keyword would be delayed gratification. A group of people should be a healthy mix of patient and impatient people, as impatient people can help patient ones to force a conclusion where patient people might otherwise never reach one.

Trust is primarily environmental and depends almost exclusively on upbringing. Childhood environment determines whether trusting or paranoid strategies are more advantageous, which are then brought into adulthood.

Loyalty is an extension of trust which helps individuals in cases of breaches of trust. Depending on environment, loyalty or disloyalty may be more advantageous. Also serves as a protection against short term gains by abandoning individuals, groups or causes.

Temperament-based personality trait. Believing or disbelieving in a cause can both be reasonable under the right circumstances, zealousness and cynicality describe the overall trend and tendencies for a person. However, this is always compared to some objective measure of how likely something is to happen.
In other words, always and constantly disbelieving in winning the lottery is not cynical, as they are just right and probably themselves underestimate just how unlikely the odds really are.

Compassionate characters are rare individuals which truly, truly care about the people around them and are able to value them as humans. Note for this, that I assign personality traits exclusively on what I was able to myself confirm. This means that I might have met hundreds of compassionate people but just missed it/don't know them well enough (yet). The absence of a trait does not mean that they are not compassionate.

Overall measure of confidence in choices or, in absence of that, temperament. Temperamentful characters are unwilling to change course.
