Perfect example Corey, thanks for sharing!
I was a big Michael Jordan fan when I was a kid. I thought he must be the perfect human being. I think that 'halo' effect is one of the mental shortcuts we've evolved to have when making judgments. After some of my other favorite celebrities were shown to be doing some things I didn't like at all, it made me rethink my binary approach to 'heroes and villains' in general. Michael Jordan may still indeed be the best guy in the world, but I realized he might be a complete jerk too. So I started thinking about specific attributes in context and fighting against the halo effect as much as I could.
