Cory Doctorow points out flaws in casting reputation as an economic system; it is not a measurable quantity and can be shown to turn out to be a currency that people game in a way that dilutes its intent.
Currencies need to serve as units of account – so you can price everything from vintage Star Wars figures to anti-fungal cream and calculate their total worth. They need to serve as media for exchange, so that someone who has Kenner Star Wars figures and needs anti-fungal cream can convert one to the other. They need to serve as stores of value – so you can convert your action figures to something more stable that you can use in your dotage, in case Star Wars ceases to be cool in another 50 years.
Reputation is pretty much useless for any of these things. Instead, they’re literally popularity contests: ‘‘more people like me than you, so I win and you lose.’’ In theory, this kind of jerky behavior will cost you reputation – but in reality, many people are delighted to treat such jerks as ‘‘strong, decisive people who tell it like it is.’’
The Internet has been trying to figure out how to make reputation work for decades now. Those scores that appear next to Ebay sellers’ names and on the profiles of ‘‘sharing economy’’ workers profile pages – Uber, Lyft, Airbnb – attempt to establish a basis for strangers to trust one another.
