In the 1730s, Benjamin Franklin had a colleague in the Pennsylvania legislature who couldn’t stand him. The man gave long speeches against Franklin, blocked him at every turn, and made clear he had no interest in being won over by charm or persuasion. Franklin didn’t try flattery. He didn’t do the man a favor either, which is the move most people would reach for first. Instead, he asked the man for one.
Franklin had heard the legislator owned a book that was hard to find anywhere else, so he wrote a short note asking to borrow it for a few days. The man sent it over. Franklin returned it a week later with a note of thanks, and something shifted: the rival started speaking to him, warmly, and eventually the two became allies for the rest of the man’s life. Franklin wrote down what he took from the whole episode, in a line psychologists still quote more than 250 years later.
The lesson Franklin wrote down for himself
In his autobiography, Franklin summed up what he took from the episode in a single sentence: “He that has once done you a kindness will be more ready to do you another than he whom you yourself have obliged.” It reads like a proverb, but Franklin seems to have meant it as something closer to a field note. He’d tested it on a man who actively disliked him, and it held up.
The logic runs backward from how most people assume favors work. The common wisdom is that if you want someone to like you, you do something nice for them first. Franklin’s version flips that around. Ask for something small, let the other person help you, and the favor itself seems to do the persuading. It’s an odd thing to stake a relationship on, especially with someone already against you. Franklin staked it there anyway, and it paid off.
Two centuries later, researchers tried it on strangers who had nothing at stake
Franklin’s anecdote sat as a curiosity for a long time before anyone tested it under controlled conditions. In 1969, psychologists Jon Jecker and David Landy ran an experiment built almost entirely around his idea. College students who had just won money in a contest were approached afterward by the lead researcher. Some were asked to do him a personal favor and return part of their winnings, on the grounds that he needed the funds for his own research budget. Others weren’t asked for anything, and a third group was told a university fund, not the researcher himself, had paid them.
Afterward, everyone rated how much they liked the researcher. The participants who had done him the favor rated him the highest of any group, higher even than the ones who owed him nothing. As a 2024 summary of the research put the study’s own conclusion: “Under certain circumstances, when an individual performs a favor for another person, his liking for that person will increase.” These were strangers with no history and no rivalry to smooth over. The favor did the work on its own.
It’s a pattern that shows up outside politics too. Two coworkers who’ve never gotten along, a new neighbor who keeps a polite distance, a classmate who’s made it clear the feeling isn’t mutual: the instinct in all of these cases is usually to try to smooth things over by being generous first, bringing over a plate of food or offering an unsolicited hand with something. Franklin’s story suggests the more effective move might run the other way.
Why asking might land better than offering
The explanation researchers point to has less to do with the person receiving the favor and more to do with the person granting it. Doing something helpful for someone you don’t especially like creates a small kind of friction: you’ve just acted generously toward a person your attitude says you shouldn’t bother with. That mismatch is uncomfortable enough that the mind looks for a way to resolve it, and adjusting the attitude is a lot easier than taking back the favor. I did something kind for him, the reasoning goes, so I probably don’t dislike him as much as I thought.
A second piece of this has nothing to do with discomfort. Asking someone for help is a small vote of confidence. It tells them you trust them to be capable and generous, which is a nicer thing to hear than most rivals expect from each other. Doing someone an unrequested favor doesn’t send that same message. It can even land as a little presumptuous, as though you’ve decided on your own that they needed the help.
Where the trick works, and where it thins out
The original research here is old and the sample sizes involved are modest by today’s standards, so it’s worth holding the finding loosely rather than treating it as settled law. What does seem to hold up across later versions of this idea is that the type of request matters. A social ask, like requesting someone’s opinion or a small piece of their expertise, tends to work better than a transactional one, like asking to borrow money. Timing seems to matter too: the effect shows up more reliably early in a relationship, before two people have settled into fixed opinions of each other.
This isn’t a script to follow line for line. Asking someone for a favor purely to engineer how they feel about you tends to be obvious, and getting caught doing it usually costs more goodwill than the original distance ever did. The version that actually works is the plain one: a genuine, small, specific ask, made because the thing is actually wanted, not because it tested well in a study.
Franklin never framed his discovery as a technique. He described it more like an observation about how people work, one he happened to test on a man who wanted nothing to do with him. The lawmaker who wouldn’t speak to Franklin lent him a book, and once he had, the two of them finally had something to talk about.
