The Secret of Effective Motivation - Intrinsic vs instrumental

NY Times     THERE are two kinds of motive for engaging in any activity: internal and instrumental. If a scientist conducts research because she wants to discover important facts about the world, that’s an internal motive, since discovering facts is inherently related to the activity of research. If she conducts research because she wants to achieve scholarly renown, that’s an instrumental motive, since the relation between fame and research is not so inherent. Often, people have both internal and instrumental motives for doing what they do.

What mix of motives — internal or instrumental or both — is most conducive to success? You might suppose that a scientist motivated by a desire to discover facts and by a desire to achieve renown will do better work than a scientist motivated by just one of those desires. Surely two motives are better than one. But as we and our colleagues argue in a paper newly published in the Proceedings of the National Academy of Sciences, instrumental motives are not always an asset and can actually be counterproductive to success.

We analyzed data drawn from 11,320 cadets in nine entering classes at the United States Military Academy at West Point, all of whom rated how much each of a set of motives influenced their decision to attend the academy. The motives included things like a desire to get a good job later in life (an instrumental motive) and a desire to be trained as a leader in the United States Army (an internal motive). [...]

Remarkably, cadets with strong internal and strong instrumental motives for attending West Point performed worse on every measure than did those with strong internal motives but weak instrumental ones. They were less likely to graduate, less outstanding as military officers and less committed to staying in the military.

The implications of this finding are significant. Whenever a person performs a task well, there are typically both internal and instrumental consequences. A conscientious student learns (internal) and gets good grades (instrumental). A skilled doctor cures patients (internal) and makes a good living (instrumental). But just because activities can have both internal and instrumental consequences does not mean that the people who thrive in these activities have both internal and instrumental motives.

Our study suggests that efforts should be made to structure activities so that instrumental consequences do not become motives. Helping people focus on the meaning and impact of their work, rather than on, say, the financial returns it will bring, may be the best way to improve not only the quality of their work but also — counterintuitive though it may seem — their financial success.[....]
