We are pre-programmed to sum people up quickly, within the first few seconds of sight or hearing. It's part of our primeval protection which still works, albeit subconciously.

Jeremy Beadle, one of the most disliked men on TV was universally accepted by his peers as a wonderful professional, and thoroughly nice guy.
