Briefest Announcement

See that greenish circle-y thing around my face? I’m now a Medium Member! It feels good to contribute to this community, both so that writers can earn something for their work directly from readers and so that Medium can continue to exist. I don’t know about you, but I get some satisfaction when I really enjoy a members-only post and, in a few clicks, help the author take the smallest step towards turning their passion into their livelihood. Also, this means that I can finally Highlight members-only posts! Will I also start posting some members-only stories? Only time will tell.

Something got me excited this week. I was just scrolling through my psychology twitter feed when I came across this tweet:

Preposterous. One of my absolute favourite psychological theories predicts (and has, for the most part, empirically demonstrated) that extrinsic rewards do sap intrinsic motivation. Now results indicate that short-term financial incentives don’t reduce long term intrinsic motivation? Blasphemy!

But what if it’s true? At the very least, the study (very well explained by the senior author in the Chicago Booth Review article; you can also find the draft here) raises important questions. Assuming the results are not a fluke, what do they mean for self-determination theory (SDT)? Even if behaviour went back to baseline, did the quality of motivation for the behaviour change? Does the effect on motivation depend on the amount of money offered as a reward? Would the effect show up in a different experimental paradigm? I hope many interesting studies spring out of this one.

In the meantime, I couldn’t resist going on Google Scholar to find out if the study has already been cited. It has! Another study seems to have found that timing of rewards matters—earlier rewards increase, rather than decrease, intrinsic motivation. However, the authors defined intrinsic motivation differently from the SDT-definition, which made me even more curious. I searched around to see what one of the authors (Fishbach) has been up to, and found two more papers: one where the authors introduce their definition of intrinsic motivation as “means-ends fusion” (PDF) and one entitled “three sources of motivation” (PDF).

I’m very excited to dig into these papers when I have time, maybe you’ll find them interesting, too. Now, while I spend the rest of my weekend trying to catch up on assignments, go have fun, you have a lot to read!
