on attitudes and emotions shows that a moderate,
unbiased person is able to see many points of
view on a hot-button, emotionally-involving
issue, whereas a radically-committed person
cannot judge all positions equally fairly. You
can see that in any “debate” where extremists
are shouting at one another (such as on Youtube).
Moderate people do not experience such
“judgmental bias,” and they can understand the
many points of view. But when people listen
to and then agree with and personally endorse
extreme speech, then their own personal judgment
scale becomes skewed and polarized into “the
good side” (theirs) and “the bad side” (their
“opponent’s” side). But there weren’t “sides”
before they endorsed the radical speech.
Endorsement operates like an infection, invading
the person’s judgment scale and slanting and
biasing their judgment processes.
