Kerbal stupidity & courage

[surge]

After a search for this, I found a billion old forum posts here and from many other sources, but they were all asking the same question:
"Does it matter?".

As an long-time player I know it does not, but on the same vein; I was looking through the astronaut complex recently for new hires and remembered something: Some kerbals in old versions used to scream their little heads off during the entire ascent of a rocket (particularly Bill), which I found very amusing. I've been keeping an eye out for the least couragous and smartest kerbals, which I suspect causes this.

They seem to have nerfed the hell out of it since... I dunno, 1.1? Because even during missions where I'm supposed to make kerbals pass out, they are usually still rubbing goo off their hands or adjusting their helmets and smiling

What causes the panicy screaming, is my question?

And I suppose, what traits aside from "BADA55" (yeah, yeah, we know) tends to cause other behaviour... for those who try to look up this question in the future.

IIRC low stupidity and low courage would cause the screaming originally? and BadA55 meant that they were immune to it. I can't say what the current behaviour is, I ignore the portraits usually.
