How tests and wrong answers help us remember what we learn
Previous research has shown that if you're young and healthy, mistakes enhance learning. But people with memory impairments, such as ageing, benefit most from error-free learning. New research challenges all of this. Researchers found that the types of clues make the difference.
If the test is conceptual (relating new learning to information we already know), young and older people remember more from a test they didn't get right. For example, asking to name a pastry, followed by feedback that "it was a tart", rather than just giving the answer without being tested on it. With non-conceptual information, errors will not help.

When a person wanting to give the test provides the DNA sample through the saliva, the company checks for variance in the saliva, as 99.9 percent of the DNA is the same in humans.
While we may not like to admit this, we all are making a lot of bad decisions, be it our personal lives, careers or in our jobs. Here is what research says about making good decisions:
If there is too much information, we tend to make the wrong decision, and even if our decision is well-researched and considered right, we end up dissatisfied.
The right information, even if less, provides clarity to make the right decision.
A gut feeling, or an instinct, is often the right path, and points towards the right decision.
Ultra-rational, logical and unemotional decision-making does not guarantee that the decision taken will be the right one.
