Moreover, you don't even need to get to the "testing" step in a lot of cases. Are people going to like your spicy anchovy and cottage cheese pizza topped with ice cream? Answer: no. I didn't have to interact with a single customer to know that. Other ideas are not so obviously bad, but I feel like a lot of these failed startups would not have existed in the first place if the founders had been really honest with themselves. If you don't have a reasonably strong belief that your idea is going to work, why bother testing it at all? At the least, you should probably try it on a tiny scale first (i.e. on yourself or a few friends) before taking investments, hiring employees, etc.
