One interesting discussion in the podcast was when Roberts and Hanson ask why, if you take a date out to an expensive dinner to signal your prosperity, you do not just show them a bank statement instead? If they answered this in the podcast, I missed it, which is possible because the discussion seemed to lack path dependence. It seems like it has a simple explanation:
- A bank statement signals wealth, but not your propensity to spend it on your new potential mate.
- A bank statement does not send as much information about future wealth as an expensive meal does, which you must pay off on your next credit card bill.
