Short of time? Read the key takeaways. Politics can feel like an endless tug-of-war that leads to gridlock. We wanted to know whether there are policies that people across the political spectrum already agree on. Such policies might offer a way to improve people's lives without needing to first resolve our deepest disagreements. ️ We found dozens of policies that appealed to people on the political Left, Center, and Right alike. In each case, even the least receptive ideological group...

Short of time? Read the key takeaways. Academic papers are worth seeking out more than most people do. They're often the only place where specific studies exist, and they can offer the most rigorous analyses available on a wide variety of topics. This article is designed as a practical guide to overcoming those barriers. Method 1: Academic databases like Google Scholar are usually the best starting point. In fact, studies indicate that Google Scholar has especially broad coverage, so...

Short of time? Read the key takeaways. Value to others beats personal interest. A common mistake creators make is assuming that what fascinates them will fascinate their audience. If you value impact, we recommend focusing instead on what your specific audience finds useful, actionable, or genuinely relevant to their lives. Your impact depends on comparison, not just quality. What matters is how much more value you provide compared to available alternatives. If similar creations already...

Note: This is a longer and more technical report of our study into personality traits. If you want to see the shorter, more layperson-friendly version, click here. There's a debate that has raged in academic journals and among personality researchers about the nature of humans: how many dimensions does it take to best represent a person's personality? Or, put another way: how many attributes would you have to score someone on to have a good sense of what they are like? We've collected new...

Short of time? Read the key takeaways. Some personality models are empirically derived. The Big Five personality model analyzes personality in terms of: Openness (to Experience), Conscientiousness, Extraversion, Agreeableness, and Neuroticism (also known as ‘emotional instability’) This model emerged from the lexical hypothesis, which claimed if a personality difference matters, languages will eventually invent words for it. Factor analysis of thousands of personality adjectives across...

Short of time? Read the key takeaways. A lot of your actions are habitual. Studies suggest that perhaps as much as two-thirds of actions are performed out of habit. Because so much of daily behavior runs on autopilot, forming positive habits is one of the highest-leverage ways to improve your life and move toward your goals. Choose a habit you’re genuinely motivated to build or replace. In our research, we found that feeling highly motivated when beginning habit formation is one of the...

Short of time? Read the key takeaways. ♻️ Many self-help techniques are recycled or repackaged versions of older ideas. Mindfulness, for instance, traces back at least 2,500 years and now appears across multiple modern therapies under different names like 'defusion,' 'decentering,' and 'acceptance.' Even still, some of these technique can be extremely useful! Popular techniques often lack strong scientific backing. Cold exposure, despite its hype, showed mixed results in a 2025...

Short of time? Read the key takeaways. Averaging group judgments often beats individual ones. There are mathematical reasons why asking a crowd and averaging their answers tends to produce more accurate results than relying on a single person's judgment, even when that person is an expert. Crowds work best for two question types. They excel at (1) factual questions with definitive answers and (2) estimating what a target population will think or feel. ⚠️ Systematic bias is the biggest...

Short of time? Read the key takeaways. ⚖️ AI is a profoundly mixed technology.  Like nuclear energy, it offers major benefits (e.g., better information, education, creativity, healthcare) while also posing serious risks (e.g., misinformation, job loss, inequality, and potential existential threats). Public perception of AI is distorted by both hype and skepticism.  Many people underestimate current capabilities due to outdated experiences, bias, or backlash against hype, even as the...

Short of time? Read the key takeaways. ❤️ "Communication problems" often mask unmet attachment needs. In relationships, conflict frequently signals something deeper: a need to feel safe, understood, and secure. When these needs go unmet, they surface as stress, anxiety, and recurring friction. Losing connection triggers a primal panic response. Humans are wired to rely on close relationships for emotional regulation. Research shows that a partner's presence, especially in a high-quality...

Image depicting a gyroscope Short of time? Read the key takeaways. Fabricated options feel real but aren't. Plenty of things that seem imaginable are actually inconsistent or impossible. This even applies to decision making contexts. You might imagine your options are A and B, without noticing that careful examination reveals that one of those options is inconsistent or impossible. It's a fabricated option . ⚠️ Fabricated options disguise uncomfortable tradeoffs. When we face difficult...

A lot of people are worried about AI.  What are their worries? How worried are they?  Are some demographics more worried than others? We ran a study to find out.  In this article, we explain 16 concerns about AI that you might find it valuable to know about. We discuss, based on our data (collected in October 2025), how...

Short of time? Read the key takeaways. People worry more about AI's societal impacts than its personal ones. While participants were almost evenly split on personal concern, 55% expressed high concern about societal effects, and only 2.4% were more worried about themselves than society. Misinformation, scams, and authoritarian control top the list. These three concerns ranked highest among all 16 issues studied, with participants rating them substantially more worrying than the...

This week, we’ve picked three short lessons that we think you’ll enjoy, from the folks over at A Little Wiser.

Short of time? Read the key takeaways. Willpower doesn’t seem to run on a single, depleting resource. Although hundreds of studies once supported ego depletion, many failed to replicate during the replication crisis. What remains is ordinary fatigue, boredom, and frustration, not strong evidence for a special self-control reservoir. Tailoring education to “learning styles” probably doesn’t boost learning much. Despite its popularity, high quality studies rarely find strong benefits from...

Short of time? Read the key takeaways ❓ You can be rationally confident in many beliefs while expecting some to be wrong. The Preface Paradox highlights that believing each claim is true does not require believing that all your claims are true at the same time. Belief is not binary but graded. When you say you believe something, you usually mean you have high confidence, not certainty. Treating beliefs as degrees of confidence dissolves apparent contradictions and better reflects how...

Short of time? Here are the key takeaways: ❓ Most single data points are misleading when you generalize from them. One experience or anecdote rarely supports broad conclusions about how things usually work, which is why people often draw confident but unjustified beliefs from minimal evidence. However, a single data point can still be informative by revealing possibilities. One well verified observation can show that something exists or can happen, immediately disproving claims of...

Short of time? Here are the key takeaways: ❓ People differ widely in how much they enjoy chatting with strangers. Some actively welcome it, while others strongly dislike it. Because you can’t reliably tell in advance, good conversations start with sensitivity to signals of interest or disinterest. Conversations get easier when you steer toward what the other person cares about. Asking what they’re genuinely interested in, and then following up thoughtfully, often leads to faster, more...

Short of time? Click here to read the key takeaways.  Sociopathy is closely related to psychopathy and antisocial personality disorder. The three terms are often used in slightly different ways, but they usually refer to the same collection of traits. 'Sociopath' is more of an informal term, and although 'psychopath' has been used in past research, the norm today is to talk in terms of antisocial personality disorder. Sociopaths tend to pursue goals without emotional brakes like guilt...

Short of time? Click here to read the key takeaways.  The word ‘why’ hides multiple different questions. An animal behavior scientist from the 1960s noticed that, when we ask ‘why’, we could be asking multiple different questions. About mechanisms, individual development, fitness effects, evolutionary history, or intentions. Different ‘why’ questions explain the same behavior in different ways. A single action, such as procrastination, can be explained using each of the different...

Short of time? Read the key takeaways News outlets are structurally biased toward negativity. Violent, tragic, and catastrophic stories reliably attract more attention and engagement, giving media organizations strong incentives to emphasize bad news even when positive or improving trends exist in the real world. Consuming lots of negative news can harm mental health. Many studies link exposure to negatively framed news with worse mood and affect, helping explain why frequent news...

Short of time? Read the key takeaways Most anecdotes about treatments are very weak evidence. Individual stories of improvement are usually explained by misattribution, placebo effects, natural recovery, or random fluctuations. For this reason, anecdotes should generally be treated with skepticism rather than taken at face value. ⚖️ Under rare but identifiable conditions, a single anecdote can provide strong evidence. When an improvement is accurately reported, dramatic, quick,...

Short of time? Read the key takeaways. People rely on relational dynamics to judge cultishness.  When people rate groups as cult-like, they focus most on signs of control, isolation, and suppression of outside information rather than on unusual predictions or strange practices. Discouraging outside information is the strongest red flag.  The clearest single predictor of perceived cultishness is when a group tries to limit members’ access to alternative viewpoints. People appear highly...

Short of time? Click here to read the key takeaways! We ran a study to better understand the moral judgments of people in the US, and we found striking disagreement. When participants rated the immorality of scenarios, a substantial share of them routinely gave maximally opposite  judgments (0.0 vs. 5.0). Many scenarios showed almost as much disagreement as a totally random spread of answers, and extreme ratings (0.0 or 5.0) were surprisingly common (26% of all ratings). So far from being...

Short of time? Click here to read the key takeaways! A 71% increase can sound alarming, but without context, it can mislead. In the aspirin example, the relative increase is 71%, yet the absolute risk only rises from 0.18% to 0.31%. Both figures are correct, but they create very different impressions of the underlying risk. Relative and absolute percentages answer different questions. Absolute change measures the direct difference between starting and ending values, while relative...

Short of time? Click here to read the key takeaways. Some economists argue that gift giving destroys value. Because givers rarely know recipients’ preferences as well as they know their own, many gifts are worth less to the recipient than the money spent, creating what economists call “deadweight loss.” One estimate suggests billions of dollars in value are lost each holiday season. However, the “market value assumption” may miss the bigger picture. Some economists assume that a...

Key Takeaways Habits shape your life outcomes. From health to happiness to career success, much of what determines your future stems from your daily routines. Simple habits can snowball into major life improvements when maintained consistently. Building habits isn’t about hitting a magic number of repetitions. While automaticity helps, habits rarely become effortless. Factors like environment, motivation, and habit complexity matter far more than repeating a behavior a set number of...

Key Takeaways We ran a large U.S. study to understand how people make moral judgments. Our goal was to see which moral principles best explain why different people view moral situations as right or wrong. We discovered 15 core moral dimensions that strongly predict people's judgments. Together, these 15 factors do a good job of explaining how most U.S. Americans respond to moral scenarios. We developed a new way to measure and predict moral intuitions using personalized models. ...

Consider the following hypothetical scenario (warning: some will find it disturbing): Poe lives alone with their dog for many years, when one day the dog runs onto the street and is lethally hit by a car. Poe, while heartbroken about losing their dog, has heard that dog meat is supposedly delicious, so decides to cook and eat it. How immoral would you consider Poe's action in this situation? Some people think it's not at all immoral - others think it's moderately so, but not nearly as bad as...
