Nice! In case anyone is interested in the science of this effect and it's surprising power, this is an almost exact reproduction of an experiment, in the field of "connection science" or "social physics". (NOTE: The true value here is in the CROSS-INCENTIVIZATION with an existing social relationship, not just the money) The general truism that falls out of it is: When possible, always apply incentives to the social f…
I’m having a hard time understanding what you mean. Can you give some examples?
Assume partner (A) and (B) have existing social ties, ie. they're not strangers, and the closer, the better.
Options: (experimenter says)
1. "Hey A and B, for every day you meet your fitness goals, I'll give you 25¢"
2. "Hey A, for every day that B meets their fitness goals, I'll give you 25¢. Hey B, same goes for you."
With proper mechanism design, dollar for dollar, option (2) can be up to 30x more effective than (1).
At least in Pentland's studies, the dollar amount is token and intended to be so small as to be negligible. It being an excuse to strengthen the social relationship (around the new activity) is where the power to change behavior comes from.
