The ad man who invented brainstorming promised twice the ideas. He had it backwards. Psych myths, #4 Alex Osborn sold the world on group brainstorming. His own book claimed the average person "can think up twice as many ideas when working with a group than when working alone." In 1958, researchers tested it. Four people working alone, with duplicates removed, came up with nearly twice as many different ideas as four people brainstorming together. The cleanest takedown came later, in a 1987 Journal of Personality and Social Psychology paper from the University of Tübingen: "Productivity Loss in Brainstorming Groups: Toward the Solution of a Riddle." In one experiment, four-person groups brainstormed out loud for 15 minutes and produced about 56 ideas. Four people working alone produced 106. Same number of brains. Almost half the ideas gone. Laziness and fear of looking dumb mattered a little. The big killer was waiting your turn. While someone else talks, you sit on your idea, forget it, or decide it isn't worth saying. When the researchers made people working alone wait for a signal light before speaking, their output crashed to group levels. And no, it isn't one odd study. A 1991 meta-analysis pooled 20 studies and 2,577 people. Groups lost on number of ideas and on rated quality, and the bigger the group, the worse it got. So the classic "let's all throw ideas out there" meeting is a leaky way to collect ideas. A couple of people fill the air, and everyone else walks out with thoughts nobody heard. Next time you run one, say this before anyone speaks: "Take five minutes. Everyone write your ideas down alone, then we'll go round the table." That's practical advice built on these findings, not a script anyone tested. The honest limit: these were lab studies, mostly students, mostly groups of four on set topics. The few studies that found no loss all used pairs. And the research counted and rated ideas, not whether the final decision was better. More psych myths coming. #psychology #neuroscience

People expect solitude to feel better on the train. They get the direction wrong. University of Chicago researchers Nicholas Epley and Juliana Schroeder tested that forecast in a 2014 Journal of Experimental Psychology: General paper, "Mistakenly Seeking Solitude." In a survey of 203 people, 76% said they would skip talking to a stranger on a train. Waiting rooms hit 93%. Most of us treat the person six inches away like furniture. Then they put the habit on a real commute. On Chicago Metra trains, 97 riders were told to connect with a stranger, sit in solitude, or ride as usual. People told to connect reported a clearly more positive commute than people told to sit alone. Conversations lasted about 14 minutes on average and rated 5.1 out of 6 for pleasantness. Reported productivity did not drop. A separate group of 66 riders predicted the opposite. They expected connection to feel worse than solitude, and less productive too. Wrong on both. The same flip showed up on public buses (75 riders in the experience study). Connection beat solitude again. Predictors still guessed solitude would win. Why does the mistake stick? Commuters rated their own interest in talking higher than they thought others felt. They guessed fewer than half of strangers would be willing to talk. When a seatmate was actually there, connection attempts worked far more often than that gloomy forecast implied. Example: you take the same morning train every day. Headphones in. Eyes down. You tell yourself the other person wants quiet. You never check. Small action for the next ride or waiting room (practical advice, not a script the paper tested): take the headphones off for two stops. Say hello to the person beside you and ask one ordinary question about their day. Stop if they shut it down. The paper's results say refusal is less common than people expect. Honest limit: Chicago field samples, self-report after the ride, and people who agreed to be studied. Partners in the field were not measured the same way (a lab waiting-room study found people who were talked to felt about as good as people told to talk). This is about short stranger chats in public, not forcing a deep conversation on someone who is clearly busy or unsafe to approach. The solitude you protect among strangers is often a forecast error. Test it once. #psychology #neuroscience

Your "calm down" pep talk never actually calms you down. Say This Instead Right before a pitch, a status update, or a meeting with your boss, most people whisper the same useless line to themselves: "Just calm down." Harvard Business School researcher Alison Wood Brooks tested that advice in a 2014 Journal of Experimental Psychology: General paper, "Get Excited: Reappraising Pre-Performance Anxiety as Excitement." In a survey of 300 people, 90.97% said they would try to relax and calm down before a high-stakes company speech. Open-ended advice from strangers landed in the same place about 85% of the time. Then the lab work. Heart rate jumped once people learned they had to sing, speak, or grind through a timed math test, and it stayed high. Telling people to remain calm did not bring it down. What did move the needle was a three-word swap. In karaoke, people who said "I am excited" out loud hit 80.52% singing accuracy. Saying nothing got 69.27%. Saying "I am anxious" sank to 52.98%. In a camera speech about why you'd be a good work partner, the "I am excited" group spoke longer (167 vs 132 seconds) and was rated more persuasive, confident, competent, and persistent than the "I am calm" group. Anxiety scores barely moved either way. The body stayed revved. The label changed. A 2025 direct replication (Poynter and Pasqualini) got the same feeling shift: "I am excited" made people feel more excited without making them feel less anxious. Judges did not rate the speeches differently. So treat the performance claim as mixed. The feeling claim held. Next time your chest is buzzing before you talk, say this instead: "I am excited." Out loud, once, right before you start. Practical advice, not a cure for clinical anxiety. The honest limit: these were mostly student samples, and the speech performance bump failed a direct replication. What still holds is the wasted calm-down ritual. Your heart does not obey it, and the usual line trains you to fight the arousal instead of using it. Stop trying to shut the engine off. Rename it. #psychology #neuroscience

The cleanest way to waste someone's trust never needs a false word. Rogers, Zeckhauser, Gino, Norton and Schweitzer (Harvard / Wharton) named that move in a 2017 Journal of Personality and Social Psychology paper, "Artful Paltering: The Risks and Rewards of Using Truthful Statements to Mislead Others." Paltering is using true statements on purpose to leave a false impression. Not staying quiet. Not inventing a fact. A true sentence aimed the wrong way. Across 2 pilot studies and 6 experiments, they tracked how common it is and what it costs once people catch on. In a Harvard Business School negotiation class, 52% of 184 experienced executives said they paltered in some or most of their deals. Only 21% said they lied with false statements that often. People also preferred it. In a study of 550 people selling a used car with known engine trouble, 71% chose the true-but-misleading reply when that was the option. Only 55% chose an outright lie, even though the lie paid better on paper. The short-term win is real. In a chat negotiation, buyers told to palter earned 16% more profit when a deal closed. Impasses also jumped: 15% versus 2% when buyers were told to be honest. Then the part that fools the palterer. After the truth came out, sellers rated the palterer's honesty at 2.8 out of 7. The palterers rated themselves at 5.0. Same behavior. Totally different story. Targets treated revealed paltering about as harshly as an outright lie. Less trust. Less willingness to deal again. Most people never find this out. You walk away thinking "I told the truth." They walk away thinking "I got played." Example: someone asks if the project is on track. You say "We hit every milestone last quarter" while this quarter is already slipping. Every word is true. The picture is wrong. Practical advice (mine, not a line the paper tested): if someone asks a direct question, answer the question they asked, not the safer nearby fact. Try: "Short version: yes, there's a risk this quarter. Want the details?" Honest limit: mostly negotiation and car-sale scenarios, often online or with confederates. True sentences can still leave a false picture. Don't hide behind them. #psychology #neuroscience

Complaining about how good you are lands worse than just bragging. Say This Instead The line that quietly ruins you at work sounds like this: "I'm so exhausted from being the only person my boss trusts with the new hires." Harvard Business School researchers Ovul Sezer, Francesca Gino and Michael Norton named that move in a 2018 Journal of Personality and Social Psychology paper, "Humblebragging: A Distinct and Ineffective Self-Presentation Strategy." Across 9 studies, including a week-long diary and a field experiment, they tracked bragging masked by a complaint or by fake humility. In a U.S. sample of 646 people, 70.1% could recall a humblebrag from someone they knew. About 1 in 5 of those came from a coworker. Looks, money, and work performance were the top topics. In a diary week, people heard one on nearly half of weekdays. Only about 9% went a whole week without catching a single one. Then the cost. People who viewed humblebrags liked the speaker less than people who viewed a plain brag (3.18 vs 3.79 out of 7). They also rated them less competent. The driver was sincerity: humblebraggers scored 3.64, straight braggers 4.31. Complaint-based ones were the worst. "Ugh, so tired of being the go-to" got liked less than the humility version ("I can't believe they nominated me"), and even less than a bare complaint with no brag inside it. Most people never find this out. Wrapping the flex in a sigh was supposed to make you look modest. It made you look fake instead. Next time you catch yourself about to do it, say this instead: "I led the new-hire training this week." Or, if you're actually tired, just say that: "I'm wiped from training." Skip the status wrap. Example: after a late close, don't post "Guess who got stuck closing the deal again." Write "Closed the deal. Going offline." The honest limit: these were mostly short statements rated by strangers, and the diary work was correlational. A boss who already trusts you may shrug. The pattern still held from Twitter posts to face-to-face asks. Don't hide the win inside a complaint. Own one or the other. #psychology #neuroscience

308,849 people. A thin social life tracked with early death about as strongly as smoking. Brigham Young University researchers pooled 148 studies for a 2010 PLoS Medicine meta-analysis, "Social Relationships and Mortality Risk." People were followed for 7.5 years on average. Those with stronger social ties had 50% higher odds of still being alive at the end. The authors called that comparable to quitting smoking, and bigger than obesity or physical inactivity. Most of us would never guess it. We count steps and protein. Nobody counts how many rooms we walk into where people know our name. And that turned out to be the part that mattered most. Getting help from others wasn't clearly linked to survival at all. The strongest signal, an odds ratio of 1.91, came from measures of how woven in you are: partner, friends, family contact and the groups you belong to, all counted together. So a social life can shrink to a partner and a phone and feel completely normal. On these measures, that's what low integration looks like. Example: you used to have a Thursday run club and a Sunday dinner. Work got busy, both faded, nobody chased you. Nothing felt wrong. The small fix: this week, put one recurring thing back on the calendar with the same people. Same day, same place. A class or a game night works. That's my practical read of the data, not something these studies tested. The catch: this is observational. You can't randomly assign people friends, and sicker people may pull back first. Results also varied a lot between studies. A 2015 follow-up that controlled for more factors still found 26% to 32% higher odds of death for loneliness, isolation and living alone. Quick test: count the places where someone would notice if you didn't show up. If the answer is zero, start there. #psychology #neuroscience

One word you use at work is quietly making people's notes on you vaguer. Say This Instead The word is "feedback." A 2025 Management Science paper, "Eliciting Advice Instead of Feedback Improves Developmental Input," tested it inside a real 360 review at a UK public-sector organization, with researchers from Harvard Business School, Imperial College and the UK's Behavioural Insights Team. Reviewers were randomly given one of two prompts about a colleague's areas to develop. Some were asked for their feedback. Others were asked for their advice for the future. Across 27,432 written comments, the advice group wrote more concrete notes. Same length. Less mush. Then the lab made it look worse. 612 people critiqued the same so-so cover letter. Blind raters scored the "advice" comments as more actionable (3.30 vs 2.86 out of 5) and more useful. And asking for "thoughts" did even worse than "feedback." The likely reason is time. "Feedback" pulls people backward into grading what you already did. "Advice" pushes them toward what you could do next, and that forward focus carried the effect in the lab data. Most people never find this out: just begging reviewers to "be specific" didn't help. In a separate test on 45,693 reviews, telling people to include concrete details didn't make their input any more concrete. So that "Any feedback?" after your presentation is practically asking for "Looks good!" Next time, say this instead: "What advice would you give me for the next version of this?" Example: you send your manager a draft deck. Swap "Thoughts?" for that line and see if you get one sentence you can actually act on. The honest limit: the effect in the real reviews was small, and a month later employees didn't rate the advice comments as more helpful. It probably won't help when you want a verdict or a post-mortem either. Ask about next time, not last time. #psychology #neuroscience
