You don't need to assume that things are normally distributed to be a Bayesian.

People who calibrate themselves usually don't get more confident through the process but less confident.

I could have calibrated on every day leading up to one of those days and felt confident in my ability to predict the stock market... but just one of those days could have wiped out my portfolio.

Don't calibrate on a single variable.

You don't need to assume that things are normally distributed to be a Bayesian.

But you do need to assume that somehow you can predict novel events based on previous data

Just going back to my stock market example, what variables would I have calibrated on to predict 9/11 and it's effects on the stock market?

I'm not arguing that you can predict the stock market. What you can do is calibrate yourself enough to see that it's frequently doing things that you didn't predict.
