>Neuroticism is one of the Big Five higher-order personality traits in the study of psychology. Individuals who score high on neuroticism are more likely than average to be moody and to experience such feelings as anxiety, worry, fear, anger, frustration, envy, jealousy, guilt, depressed mood, and loneliness.[1] People who are neurotic respond worse to stressors and are more likely to interpret ordinary situations as threatening and minor frustrations as hopelessly difficult. They are often self-conscious and shy, and they may have trouble controlling urges and delaying gratification.

Is there truly a common thread between these various emotions that ties them all together as neuroticism, or is neuroticism an arbitrarily chosen set of emotions? It's far from clear to me that these listed emotions have much to do with each other in the general case. If I'm feeling fear or worry because the sidewalk I'm walking on is covered in ice, that's not related in any way to anger or envy. Does it only count when these emotions are irrational? What then does it mean for these emotions to be irrational? If I am alone and feel lonely, is that irrational? Is loneliness only indicative of neuroticism when you're actually surrounded by your friends? Maybe you'd feel lonely in such a situation because none of your friends can related to you about something you've been worrying about. Is there any truly objective measure of the rationality of an emotion? I don't think so.

Wikipedia goes on to say that there's a lot of disagreement over what this term means:

> Neuroticism is a trait in many models within personality theory, but there is a lot of disagreement on its definition. Some define it as a tendency for quick arousal when stimulated and slow relaxation from arousal, especially in concern to negative emotional arousal; others define it as emotional instability and negativity or maladjustment, in contrast to emotional stability and positivity, or good adjustment. Others yet define it as lack of self-control, poor ability to manage psychological stress, and a tendency to complain.[6]

It says that 'personality theory' is a scientific study, but I'm a bit skeptical of that.

Yes. It's something that shows up in one specific factor analysis as one of five dimensions (i.e. parameters) that effectively summarize your answers to a bunch of questions about personality. Different analyses/models come up with different parameterizations, e.g. the HEXACO model has six parameters, with the Emotionality factor picking up the bulk of "Neuroticism" from the Big 5, but some ending up under Honesty-Humility (reversed) or even under Agreeableness (reversed)!

Suppose for example a woman lives in an environment that's dangerous for her but not so for men. On the questionnaire, she reports that she often feels afraid. Is that answer considered evidence of neuroticism? It seems to me that it shouldn't be, but you'd need to examine the individual circumstances on a case-by-case basis to tease out the difference between rational fear and neurotic fear. From a logistics standpoint I don't see how that analysis could be done at scale, hence my skepticism that any of this is actually scientific.

Additionally, dealing with discrimination can lead to self-esteem issues, which are tied to neuroticism.

When thinking about this you should ask what your priors are. If neuroticism is widely, across ages and cultures, found to be higher in women and men, and it is, then wouldn't your prior, without a Google specific personality survey, be that Google women likely have higher neuroticism than men?

To me it seems like an impossibly high standard to expect Damore to do a personality survey of Google to figure out if this oft repeated neuroticism result also holds true for Google employees.

Keep in mind that Damore is a single person giving feedback to a diversity course. He doesn't have the resources, time, or mandate to survey Google's employees to test whether or not this general trend holds. Perhaps, before acting on Damore's recommendations it would be a good idea to do some tests on Google's employees to see if general trends hold true in their specific subset - but that is a really different claim than the initial claim that Damore was unscientific.

If Damore had written that smoking causes lung problems and therefore Google should start taking some actions to stop employees from smoking, it might be merited to do further tests to see if the link between smoking and lung problems holds true for Google employees as it does for people in general. It would not be merited to call Damore unscientific because he had not yet done that research prior to making his suggestion.

Do you find this statement offensive? Should I not say this because it might hurt men's feelings?

Or is it only wrong to say something negative about a race/gender if it implies something negative about certain underrepresented genders and races?
