It has long been said that if you really want to learn something, you should teach it. But research shows that the same can be said for tweeting. When NeuroInsights ran focus groups with consumers who were shown programming and told they would need to tweet about it, paid more attention and retained the information better than those in the control group. So, instead of “pay attention, it might be on the test” perhaps we should say “pay attention, it might be in a tweet.”
