Cognitive bias cheat sheet. You don’t have to. But you can start by remembering these four giant problems our brains have evolved to deal with over the last few million years (and maybe bookmark this page if you want to occasionally reference it for the exact bias you’re looking for): Information overload sucks, so we aggressively filter. Noise becomes signal.Lack of meaning is confusing, so we fill in the gaps. Signal becomes a story.Need to act fast lest we lose our chance, so we jump to conclusions. Stories become decisions.This isn’t getting easier, so we try to remember the important bits. Your Gut Has a Mind of Its Own... Literally. Gut microbiome alterations in Alzheimerâs disease.
Color Psychology and Human Behavior. We don't actually see colors with our eyes.
We see colors with our brains. Our eyes are important for detecting and responding to light, but it is the brain's visual center in the occipital lobes that processes visual information and assigns color. The colors we see are determined by the wavelength of light that is reflected. Visible color wavelengths range from about 380 nanometers (nm) to about 750 nanometers. Different colors along the visible light spectrum have different wavelengths. Our eyes have three types of cones: blue, green, and red. Sources. We ignore what doesn’t fit with our biases – even if it costs us. People Furthest Apart on Climate Views Are Often the Most Educated. As arguments about climate change heat up, don’t underestimate your opponent.
It turns out that people who are the furthest apart in their views on a scientific issue are often the most educated and informed, according to a study published yesterday in the journal Proceedings of the National Academy of Sciences. Looking at a nationally representative survey of views on stem cell research, the Big Bang, human evolution, nanotechnology, genetically modified views and climate change, researchers at Carnegie Mellon University found that respondents with the most education and the highest scores on scientific literacy tests had the most polarized beliefs. On climate change, the researchers found that political identity was a more important signal of where respondents stood than their academic acumen or scientific sophistication. “Conservatives with higher scores display less concern about climate change, while liberals with higher scores display more concern,” the authors wrote.
When Are You Really Random? After Age 24 - The New York Times. Our Ability to Keep 'em Guessing Peaks around Age 25. The brain processes sights, sounds and other sensory information—and even makes decisions—based on a calculation of probabilities.
At least, that’s what a number of leading theories of mental processing tell us: The body’s master controller builds an internal model from past experiences, and then predicts how best to behave. Although studies have shown humans and other animals make varied behavioral choices even when performing the same task in an identical environment, these hypotheses often attribute such fluctuations to “noise”—to an error in the system.
But not everyone agrees this provides the complete picture. After all, sometimes it really does pay off for randomness to enter the equation. A prey animal has a higher chance of escaping predators if its behavior cannot be anticipated easily, something made possible by introducing greater variability into its decision-making. The study’s results may even have implications for understanding human creativity. How Technology Hijacks People’s Minds — from a Magician and Google’s Design Ethicist — The Startup.

Exercises. Performance enhancement at the cost of potential brain plasticity: neural ramifications of nootropic drugs in the healthy developing brain. 1Department of Psychology, University of Delaware, Newark, DE, USA2Department of Neurobiology and Anatomy, Drexel University College of Medicine, Philadelphia, PA, USA Cognitive enhancement is perhaps one of the most intriguing and controversial topics in neuroscience today.
Currently, the main classes of drugs used as potential cognitive enhancers include psychostimulants (methylphenidate (MPH), amphetamine), but wakefulness-promoting agents (modafinil) and glutamate activators (ampakine) are also frequently used. Pharmacologically, substances that enhance the components of the memory/learning circuits—dopamine, glutamate (neuronal excitation), and/or norepinephrine—stand to improve brain function in healthy individuals beyond their baseline functioning. In particular, non-medical use of prescription stimulants such as MPH and illicit use of psychostimulants for cognitive enhancement have seen a recent rise among teens and young adults in schools and college campuses.

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. Your Evolved Intuitions.

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. Top 10 Common Faults In Human Thought. Humans The human mind is a wonderful thing.
