Where does the term Armchair Psychologist come from? I understand it means someone who has no formal training who 'sits in their comfortable armchair' and gives (usually) unsolicited advice to others, but where does this expression come from? When was it first used, etc.? Also, why an "armchair"? Wouldn't a psychologist usually be sitting in an armchair when they're giving an analysis?

The oldest of these expressions seems to be arm-chair traveller in 1809, at least according to OED. OED also provides a good definition for the expression that explains why "armchair" is significant:

Based or taking place in the home as opposed to the world or environment outside; amateur, non-professional; (hence) lacking or not involving practical or direct experience of a particular subject or activity. Also: comfortable, gentle, easy.
