How introspection can lead to greater understanding — and how it may not.
The chicken that is fed by the farmer each morning may well have a theory that it will always be fed each morning – it becomes a ‘law’. And it works every day, until the day the chicken is instead slaughtered.
…Economics is at a disadvantage compared to the physical sciences because we cannot do so many types of experiments (although we are doing more and more), but we have another source of evidence: introspection… why is the farmer doing this? What is in it for him? If I was the farmer, why would I do this? And of course trying to answer that question might have led them to the unfortunate truth.
