Many thanks.

Yes, we only went back for those who contacted us first. Your idea is an interesting one, but it gets at something else (how many people, who otherwise would keep the wallet, instead would turn over the wallet when confronted by the owner). We collected wallets from those who contacted us to rule out the possibility that they are returning the wallets empty.

>We find that over 98% of the money was returned, so doesn't seem to be the case that people are contacting the owner but pocketing the cash.

But in the figure the highest return rate is still below 90%, this just makes me think how do you select the subset to retrive the cash?
