Subclaims¶

q3 i? Using the Intrinsic Motivation Inventory, the article finds no evidence that incentives decrease intrinsic motivation; point estimates are too small and standard errors too large to conclude anything other than a null effect. → Roland G. Fryer 2010

Evidence¶

Roland G. Fryer 2010¶

q3 · i? · causal · r2

Survey data across all four cities using the Intrinsic Motivation Inventory (Ryan, 1982). The article notes input experiments seem positively associated with motivation and output experiments negatively, but estimates are imprecise.

"Finally, using the Intrinsic Motivation Inventory developed in Ryan (1982), we fi nd no evidence that incentives decrease intrinsic motivation."
