 Mindfulness Meditation Reduces Cognitive Rigidity

Two experiments examined the relation between mindfulness practice and cognitive rigidity by using a variation of the Einstellung water jar task. Participants were required to use three hypothetical jars to obtain a specific amount of water. Initial problems were solvable by the same complex formula, but in later problems (“critical” or “trap” problems) solving was possible by an additional much simpler formula. A rigidity score was compiled through perseverance of the complex formula...

 Dunning–Kruger effect

People tend to hold overly favorable views of their abilities in many social and intellectual domains. The authors suggest that this overestimation occurs, in part, because people who are unskilled in these domains suffer a dual burden: Not only do these people reach erroneous conclusions and make unfortunate choices, but their incompetence robs them of the metacognitive ability to realize it. Across 4 studies, the authors found that participants scoring in the bottom quartile on tests of hum...

 Children are Scientists

Thousands of experiments confirm that babies learn about their environment through a series of increasingly self-corrected ideas. They experience sensory observations, make predictions about what they observe, design and deploy experiments capable of testing their predictions, evaluate their tests, and add that knowledge to a self-generated, growing database. The style is naturally aggressive, wonderfully flexible, and annoyingly persistent. They use fluid intelligence to extract information,...

 If You Wish To Contradict Bacon's Assertions, Please Use ...

I have on my own part made it my care and study that the things which I shall propound should not only be true, but should also be presented to men's minds, how strangely soever preoccupied and obstructed, in a manner not harsh or unpleasant. It is but reasonable, however (especially in so great a restoration of learning and knowledge), that I should claim of men one favor in return, which is this: if anyone would form an opinion or judgment either out of his own observation, or out of the cr...

 A Programmer's Basic Material is Knowledge

As Pragmatic Programmers, our base material isn't wood or iron, it's knowledge. We gather requirements as knowledge, and then express that knowledge in our designs, implementations, tests, and documents. And we believe that the best format for storing knowledge persistently is plain text. With plain text, we give ourselves the ability to manipulate knowledge, both manually and programmatically, using virtually every tool at our disposal.
