Experiences are the most important thing in life. Life is the product of adaptation and evolution where we as individuals and as a species, over the course of our lives and the course of eons experience the world we find ourselves in. Humanity found a way to pass on the experiences of our elders to future generations through language, and currently we are one of the most powerful species in existence on earth today. Experiences are everything in life.

And yet we ask questions like "if you could have done things differently, what would you do?" This is the most pointless question, because while it takes the persons current experiences and applies it to a past situation, usually its a situation they either couldn't have anticipated or one thats unlikely to come up again for them or anyone else.

A better question for solving problems would be "In a perfect world, which of your past experiences would fit the least in said world?" This way the onus isn't on them to fix their own problems, it forces them to identify where the problems in their life were and how removing that experience from all future lives would be a step towards a more perfect world. And since they aren't being asked to fix the problem, just identify it, it means they could be racist, sexist, bigoted, whatever, and they still can contribute without their biases getting in the way. Their solutions would be corrupted by their feelings, but those feeling stem from past experiences, and removing those experiences might abolish racism, sexism, etc.

However, removing experiences would need to be done by a unbiased system, or it would lead to further negative experiences. The goal is to only have worthwhile, educational experiences in life, and any biased system will inevitably lead to negative experiences in a few people that they would wish hadn't happened.
