Break from the Herd? Do It

I've always been a loner so when I read that it's sometimes a good idea to break away from the herd, I was all for it.

According to ScienceDaily, people learn valuable information from how long others hesitate before making their decisions, a new study suggests.

Researchers found that when people saw others in their group hesitating before making a choice, they were about twice as likely to break from the group and make a different choice, the web site reports.

"When we see other people hesitate before making a choice, that tells us they were conflicted, that they weren't entirely sure they were making the right decision," Ian Krajbich, co-author of the study and professor of psychology and economics at The Ohio State University, tells ScienceDaily. "That makes people less confident in the group consensus and frees them to make decisions based on their own information. That can help groups to escape bad outcomes."

The findings have implications for group behavior in politics, finance, fashion -- any situation where there might be herd behavior, Krajbich notes.

"Even if it appears at first that everyone is following the same trend, hesitation may reveal that they are not all on the same page," he explains. "If people start to notice that others are hesitating before joining the herd, that can stall the momentum or shift it entirely."

For example, think about a political campaign in which a candidate is seeking endorsements from popular politicians. Slow endorsements that come late in a campaign could indicate weak support and are less convincing than endorsements that come earlier in a campaign, Krajbich says.

"In each of 30 rounds, eight participants were given identical virtual bags containing three balls, each marked either 'A' or 'B' (the study was conducted on computers, using college students). One at a time, each participant pulled one ball, saw which letter was on it, and then guessed which letter appeared most frequently in the bag," the web site goes on.

Each person following could see what the previous participants guessed -- but not what letters were on those earlier balls. That left some participants later in the chain with a dilemma, Krajbich says.

Say you were fourth in line and you pulled an A ball. That would suggest there are more A balls in the bag. But you see the previous three people guessed B. You have to decide whether to go with your information that suggests guessing A, or to go with the herd and guess B.

That's where hesitation comes in, Krajbich said. If you see that the previous person in the chain waited awhile before choosing B, that may be an important signal. That previous person may have also pulled an A ball, like you did, and hesitated before choosing B with the herd. In that case, choosing A might actually make sense for you.

That's exactly how many participants interpreted situations where their information conflicted with the group, Krajbich points out. "When their predecessor responded slowly, participants chose against the herd about 66% of the time, compared to only 33% of the time when their predecessor chose quickly.

In cases where the group was making the wrong decision, this often led people to break from the herd and make the correct choice, he says. "A couple of bad decisions at the beginning can lead everyone astray. That's the herd behavior," Krajbich says. "But what we found is that if people can see the hesitation in others' choices, that can help them break the chain and change the course of the group."

The same phenomenon can work the opposite way, too. Fast decisions by others can reinforce one's own information. For example, if a person sees their friends quickly choose to get a vaccine for COVID-19, that may make them more comfortable making the same choice, Krajbich tells ScienceDaily.

If friends hesitate before getting a vaccine -- even if they eventually get one -- that may make a person less sure about whether to get the shot, he says.

This may not necessarily be a universal rule. "It will be important to figure out when fast decisions signal confidence or when instead they signal thoughtlessness," he concludes.
