Psychometrics break down into 2 branches and you would be well advised to remember this:
a) Hard - hand-eye coordination, response time, speed/time/distance computation, spatial awareness/recognition, literacy & comprehension, memory
b) Soft - leadership/followship, passivity/aggresssion, sociobility, socio-economic class, maturity, conformity/indvidualism
Most pilots and wannabe pilots have no problem with a) and a deep mistrust of b).
Well fine.
I can understand that. That used to be my inclination too. Most of what makes people want to be, or take pride in being a pilot in connected with a).
Only then I started studying pilot selection techniques as part of my degree... To summarise:
In the last 25 years there has been a growing realisation in commercial aviation that b) is as just as important as a). Hence CRM and all its connotations and derivations.
So when you are tempted to slag Psychometrics remember that they encompass both a) AND b).
I have lost jobs with BA *twice* because of psychologists at interview and b) considerations... but I still believe the evidence the hypothesis and the lab results I have read...
Good luck,
