💎 On how adding a little bit of effort into learning increases probability of remembering

In one study published in 2014, researchers from Princeton and UCLA examined the relationship between learning and disfluency by looking at the difference between students who took notes by hand while watching a lecture and those who used laptops. Recording a speaker’s comments via longhand is both harder and less efficient than typing on a keyboard. Fingers cramp. Writing is slower than typing, and so you can’t record as many words. Students who use laptops, in contrast, spend less time actively working during a lecture, and yet they still collect about twice as many notes as their handwriting peers. Put differently, writing is more disfluent than typing, because it requires more labor and captures fewer verbatim phrases. tale When the researchers looked at the test scores of those two groups, however, they found that the hand writers scored twice as well as the typists in remembering what a lecturer said.

💎 On how, once we decide upon a way of thinking, we struggle to see the other side

One important study of the power of such decision-frames was published in 1984, after a researcher from Northwestern asked a group of participants to list reasons why they should buy a VCR based on their own experiences. Volunteers generated dozens of justifications for such a purchase. Some said they felt a VCR would provide entertainment. Others saw it as an investment in their education or a way for their families to spend time together. Then those same volunteers were asked to generate reasons not to buy a VCR. They struggled to come up with arguments against the expenditure. The vast majority said they were likely to buy one sometime soon.

Next, the researcher asked a new group of volunteers to come up with a list of reasons against purchasing a VCR. No problem, they replied. Some said watching television distracted them from their families. Others said that movies were mindless, and they didn’t need the temptation. When those same people were then asked to list reasons for buying a VCR, they had trouble coming up with convincing reasons to make the purchase and said they were unlikely to ever buy one.

What interested the researcher was how much each group struggled to adopt an opposing viewpoint once they had an initial frame for making a decision. The two groups were demographically similar. They should have been equally interested in buying a VCR. At to very least, they should have generated equal numbers of reasons to buy or spurn the machines. But once a participant grabbed on to a decision-making frame—This is an investment in my education verses this is a distraction from my family

💎 On people we think of as exceptionally creative (essentially being intellectual middleman)

Modern bike helmets exist because a designer wondered if he could take a boat’s hull, which can withstand nearly any collision, and design it in the shape of a hat. It even reaches to parenting, where one of the most popular baby books—Benjamin Spock’s The Common-Sense Book of Baby and Child Care, first published in 1946—combined Freudian psycho-therapy with traditional child-rearing techniques.

“A lot of the people we think of as exceptionally creative are essentially intellectual middlemen,” said Uzzi. “They’ve learned how to transfer knowledge between different industries or groups. They’ve seen a lot of different people attack the same problems in different settings, and so they know which kinds of ideas are more likely to work.”

Within sociology, these middlemen are often referred to as idea or innovation brokers.
