An interesting thing about the linked quora question is that they do show a few examples of times scientists were generally wrong about something. If you look at them, they seem to have certain commonalities: they involve some deeply perplexing observation (either practical or theoretical), generally made by those with a deep experience of related subjects.

By contrast, the instances where scientists were all wrong do not, it turns out, look like wildly simplistic, obvious ideas conjured by those who apparently never even skimmed the wikipedia article on the subject.
