selection bias?

• whatyoucantsay 9y ago
  Yes, but not in the way you think. They selected themselves. Of course people know more of fantastic successes than those who end up in the middle or at the bottom of the heap. Many both with and without credentials fail. More of those with credentials succeed, but it is an extremely tenuous argument to claim that schooling caused its recipients to succeed rather than the more straightforward explanation that schools select those who would succeed even without them. Selection bias is a factor (along multiple dimensions) and it isn't at all clear whether universities make a net positive or net negative contribution to their pupils. One thing is clear, however. It's better to force gatekeepers to filter you out rather than do the task for them.
