Dunning-Kruger_effect from wikimedia.org. The Dunning–Kruger effect is a cognitive bias wherein relatively unskilled individuals suffer from illusory superiority, mistakenly assessing their ability to be much higher than is accurate. The bias was first experimentally observed by David Dunning and Justin Kruger of Cornell University in 1999. Dunning and Kruger attributed the bias to the metacognitive inability of the unskilled to evaluate their own ability level accurately. Their research also suggests that conversely, highly skilled individuals may underestimate their relative competence, erroneously assuming that tasks that are easy for them also are easy for others.[1] Dunning and Kruger have postulated that the effect is the result of internal illusion in the unskilled, and external misperception in the skilled: "The miscalibration of the incompetent stems from an error about the self, whereas the miscalibration of the highly competent stems from an error about others.

The Power of Positive Thinking - Can We Literally Will Ourselves to Become... When you are sick, either from something minor like a cold or from a more serious health problem, have you ever noticed how your mental attitude can really contribute to the way you feel?
I can remember throwing myself some pretty good pity parties when I was bed-ridden with the flu or pneumonia or something. Along with feeling very sorry for myself, I would think things like, “I feel so sick.” “My fever is not going away.” “This is just horrible…I’m never going to get better.” If we’re all being honest here, I think thoughts like these are pretty normal. I also had a difficult time staying positive while I was recovering from my hysterectomy. In the past few months, a few things happened that have really shown me how our thoughts and feelings can impact our health. On the other hand, my friend explained, if we make an effort to think positive thoughts about our health and how we are feeling, our bodies will “listen” and respond accordingly. Top 10 Common Faults In Human Thought. Humans The human mind is a wonderful thing.
Cognition, the act or process of thinking, enables us to process vast amounts of information quickly. For example, every time your eyes are open, you brain is constantly being bombarded with stimuli. You may be consciously thinking about one specific thing, but you brain is processing thousands of subconscious ideas. Unfortunately, our cognition is not perfect, and there are certain judgment errors that we are prone to making, known in the field of psychology as cognitive biases. They happen to everybody regardless of age, gender, education, intelligence, or other factors. The Gambler’s fallacy is the tendency to think that future probabilities are altered by past events, when in reality, they are not. Reactivity is the tendency of people to act or appear differently when they know that they are being observed. Pareidolia is when random images or sounds are perceived as significant.

Bananas and Monkeys. Original source unknown. (But the story appears to have some basis in fact.) Start with a cage containing five monkeys. Inside the cage, hang a banana on a string and place a set of stairs under it. Before long, a monkey will go to the stairs and start to climb towards the banana.
As soon as he touches the stairs, spray all of the other monkeys with cold water. After a while, another monkey makes an attempt with the same result - all the other monkeys are sprayed with cold water. Pretty soon, when another monkey tries to climb the stairs, the other monkeys will try to prevent it. Now, put away the cold water. After another attempt and attack, he knows that if he tries to climb the stairs, he will be assaulted. Next, remove another of the original five monkeys and replace it with a new one. Most of the monkeys that are beating him have no idea why they were not permitted to climb the stairs or why they are participating in the beating of the newest monkey.
