how are talking head segments in reality shows produced?

See thread title.

I am curious to the talking head segments in reality shows - is there a custom for how they are produced? Are they typically shot before a certain sequence or afterwards? I’ve seen examples that hint at both and I find it confusing - I am not too trusting of somebody who is talking about her *expectations *of something but is edited into the program to talk about what is actually going on.

I have no inside knowledge but I’ve wondered about this too and I think I know what they do.

I think they show them the tape afterwards and ask them questions like “what were you feeling at that moment?”

This seems to be the case 99% of the time, but I think some things are just plain waaaaay more scripted than we’d like to believe. I’ve definitely seen it out of order a couple times on The Biggest Loser, with haircuts/beards/makeovers being the giveaway. It confused the hell out of me last season when Dan was “reflecting” on a haircut he obviously hadn’t gotten yet.

There was a Real World (Hawaii?) where some guy kept radically changing his hair color, and I always wondered if it wasn’t to show off the hypocrisy of the “interview room”, because it makes it very clear that it’s time shifted and probably out of context, etc.

I’ve read on reality sites that they specifically ask the confessors to talk in the present tense. There have been times when that has been problematic, however, particularly when people have not understood such basics of grammar.
