Yep 100%. I thought Amanda was similar. She thought she was 'better' at finding traitors. Despite the fact she was wrong, it's not how to play the game. It's a game of survival, there's not a scenario where you take out 4 traitors in the frist 4 days, then share the money equally between everyone. You are better off staying under the radar, befriend traitors, and build up a case. Instead of finding traitors you need to find a fellow faithful and stick together. Joe and Nick almost did that in the celebrity one and it would have worked but Nick panicked and did a u-turn.
I can't remember which series (maybe Australia or New Zealand or even Canada - I've watched a lot) where someone was so blatently a traitor. A faitfhul guy argued a case to keep them in and gain info. The whole group voted him out as they couldn't get their heads round why he wouldn't want to vote a traitor out. Even after he announced he was a faithful they were gobsmaked and continued to question it - clueless
