Finance has the advantage of providing rapid and unambiguous feedback for your actions.
If you're trading yes, although the feedback is extremely noisy. If you're designing models not so much. Incidentally a lot of the quants I know are also good at doing Tarot readings, whether they believe the cards have power or not.
although the feedback is extremely noisy.
That very much depends on what kind of strategy you're trading. For example, HFT doesn't have problems with noise.
If you're designing models not so much.
Yes, so much. Your model has to work well on historical data and if it makes it to production, it will have performance metrics that it will have to meet.
