I think the fact that chemotherapy isn’t a very good example demonstrates a broader problem with this post: that maybe in general your beliefs will be more accurate if you stick with the null hypothesis until you have significant evidence otherwise. Doing so often protects you from confirmation bias, bias towards doing something, and the more general failure to imagine alternative possibilities. Sure, there are some cases where, on the inside view, you should update before the studies come in, but there are also plenty of cases where your inside view is just wrong.
