Your Evolved Intuitions

Your Evolved Intuitions
Part of the sequence: Rationality and Philosophy We have already examined one source of our intuitions: attribute substitution heuristics. Today we examine a second source of our intuitions: biological evolution. Evolutionary psychology Evolutionary psychology1 has been covered on Less Wrong many times before, but let's review anyway. Lions walk on four legs and hunt for food. Certain evolved psychological mechanisms in humans are part of what makes us like each other and not like lions, skunks, and spiders. These mechanisms evolved to solve specific adaptive problems. An an example of evolutionary psychology at work, consider the 'hunter-gatherer hypothesis' that men evolved psychological mechanisms to aid in hunting, while women evolved psychological mechanisms to aid in gathering.6 This hypothesis leads to a list of bold predictions. And as it turns out, all these predictions are correct.7 (And no, evolutionary psychologists do not only offer 'postdictions' or 'just so' stories. Notes

8 Things Everybody Ought to Know About Concentrating “Music helps me concentrate,” Mike said to me glancing briefly over his shoulder. Mike was in his room writing a paper for his U.S. History class. On his desk next to his computer sat crunched Red Bulls, empty Gatorade bottles, some extra pocket change and scattered pieces of paper. In the pocket of his sweat pants rested a blaring iPod with a chord that dangled near the floor, almost touching against his Adidas sandals. Mike made a shift about every thirty seconds between all of the above. Do you know a person like this? The Science Behind Concentration In the above account, Mike’s obviously stuck in a routine that many of us may have found ourselves in, yet in the moment we feel it’s almost an impossible routine to get out of. When we constantly multitask to get things done, we’re not multitasking, we’re rapidly shifting our attention. Phase 1: Blood Rush Alert When Mike decides to start writing his History essay, blood rushes to his anterior prefrontal cortex. Phase 2: Find and Execute

Top 10 Thinking Traps Exposed — How to Foolproof Your Mind, Part II In the first part of this article, we focused on 5 traps that hinder our ability to think rationally. As a quick recap, we discussed: The Anchoring Trap: Over-Relying on First ThoughtsThe Status Quo Trap: Keeping on Keeping OnThe Sunk Cost Trap: Protecting Earlier ChoicesThe Confirmation Trap: Seeing What You Want to SeeThe Incomplete Information Trap: Review Your Assumptions Now it’s time to complete the list and expose the remaining 5 dangerous traps to be avoided. Let’s dive right in. 6. In a series of experiments, researchers asked students in a classroom a series of very simple questions and, sure enough, most of them got the answers right. This “herd instinct” exists — to different degrees — in all of us. This tendency to conform is notoriously exploited in advertising. Conformity is also one of the main reasons why once a book makes into a well-known best-sellers list, it tends to “lock in” and continue there for a long time. What can you do about it? 7. 8. John Riley is a legend.

The Ten Most Revealing Psych Experiments Psychology is the study of the human mind and mental processes in relation to human behaviors - human nature. Due to its subject matter, psychology is not considered a 'hard' science, even though psychologists do experiment and publish their findings in respected journals. Some of the experiments psychologists have conducted over the years reveal things about the way we humans think and behave that we might not want to embrace, but which can at least help keep us humble. That's something. 1. 'Lord of the Flies': Social Identity Theory The Robbers Cave Experiment is a classic social psychology experiment conducted with two groups of 11-year old boys at a state park in Oklahoma, and demonstrates just how easily an exclusive group identity is adopted and how quickly the group can degenerate into prejudice and antagonism toward outsiders. Researcher Muzafer Sherif actually conducted a series of 3 experiments. 2. 3. 4. 5. 6. 7. 8. 9. 10. Turns out that it's all about framing.

Fixed vs. Growth: The Two Basic Mindsets That Shape Our Lives “If you imagine less, less will be what you undoubtedly deserve,” Debbie Millman counseled in one of the best commencement speeches ever given, urging: “Do what you love, and don’t stop until you get what you love. Work as hard as you can, imagine immensities…” Far from Pollyanna platitude, this advice actually reflects what modern psychology knows about how belief systems about our own abilities and potential fuel our behavior and predict our success. Much of that understanding stems from the work of Stanford psychologist Carol Dweck, synthesized in her remarkably insightful Mindset: The New Psychology of Success (public library) — an inquiry into the power of our beliefs, both conscious and unconscious, and how changing even the simplest of them can have profound impact on nearly every aspect of our lives. One of the most basic beliefs we carry about ourselves, Dweck found in her research, has to do with how we view and inhabit what we consider to be our personality.

10 More Common Faults in Human Thought | Listverse Humans This list is a follow up to Top 10 Common Faults in Human Thought. Thanks for everyone’s comments and feedback; you have inspired this second list! It is amazing that with all these biases, people are able to actually have a rational thought every now and then. There is no end to the mistakes we make when we process information, so here are 10 more common errors to be aware of. The confirmation bias is the tendency to look for or interpret information in a way that confirms beliefs. The Availability heuristic is gauging what is more likely based on vivid memories. Illusion of Control is the tendency for individuals to believe they can control or at least influence outcomes that they clearly have no influence on.

Low-Effort Thought Promotes Political Conservatism The authors test the hypothesis that low-effort thought promotes political conservatism. In Study 1, alcohol intoxication was measured among bar patrons; as blood alcohol level increased, so did political conservatism (controlling for sex, education, and political identification). In Study 2, participants under cognitive load reported more conservative attitudes than their no-load counterparts. In Study 3, time pressure increased participants’ endorsement of conservative terms. In Study 4, participants considering political terms in a cursory manner endorsed conservative terms more than those asked to cogitate; an indicator of effortful thought (recognition memory) partially mediated the relationship between processing effort and conservatism. © 2012 Society for Personality and Social Psychology, Inc.
