That might be in part because survivorship bias substitutes (in a good way!) for consideration.
For example, if a hundred new bakeries open each year, each one baking bread according to a recipe that the baker just kind of randomly put together without much thought, and ten years on, one of those bakeries is now drawing customers far and wide and five-star reviews, it makes sense to carefully consider any changes to the recipe even though it was only randomly thrown together in the first place. It might just be a winning formula that is the secret underlying their success.
Of course it might be their customer service, their casual atmosphere, or their good location that has driven that success, not the bread recipe. But it's hard to know for sure. So changes need to be done very carefully if at all!
