Practicing skepticism and always being analytical is a lot of work. Listening to the SGU podcasts shows that even when people are actively trying to be skeptics they still catch themselves shortcutting to opinions.

Let me ask you this. Take something you believe 100%, how much evidence the other way will it take for your opinion to change? Now imagine that item is somehow part of your identity. It's not an easy fight every single day.

The reason I bring this up is instead of saying 'some of these people', it's better to say all of us.
