You're right, to be prejudiced is easy however when you are dealing with complex things like people, it just doesn't seem right.
Prejudiced? I suppose you can call it that, but then prejudice also applies to conclusions reached after much deliberation and research. We can never get to 100% certainty of pegging a person's personality.
From your perspective, it seems whatever is based on less evidence or experience is less right than that which is based on more. I would tend to agree, since other methods like racial profiling still have slightly correct correlations, though in a lot of situations they are so unreliable that they probably are not worth the neurons. I think assessing a handshake is reliable enough to bother with, and I don't see why it should be considered objectively "wrong," since it is just a rougher level of estimation.
