I suspect the showrunners intentionally put in people who are bad at survival or mentally/emotionally weak (which comes out during internal testing), so that they can eliminate a few people in the early episodes.

You want at least one or two people to hear a bear and tap out in ep 1 or 2. And it has to be guys tapping out: if you include women, they have to be the hardiest contestants, so they don't tap out too early.
