No such thing as a stupid question. " (There's) no such thing as a stupid question" is a common phrase, that states that the quest for knowledge includes failure, and that just because one person may know less than others, they should not be afraid to ask rather than pretend they already know.
The book contains a selection of questions and answers originally published on his blog What If?, along with several new ones. The book is divided into several dozen chapters, most of which are devoted to answering a unique question.
Differential item functioning (DIF), sometimes referred to as measurement bias, is a phenomenon when participants from different groups (e.g. gender, race, disability) with the same latent abilities give different answers to specific questions on the same IQ test.
These included his long-running "Snappy Answers to Stupid Questions", which present multiple putdowns for the same unnecessary or clueless inquiry, and several articles on inventions and gadgets, which were presented in an elaborately detailed "blueprint" style.
Like all current IQ tests, the Wechsler tests report a "deviation IQ" as the standard score for the full-scale IQ, with the norming sample mean raw score defined as IQ 100 and a score one standard deviation higher defined as IQ 115 (and one deviation lower defined as IQ 85).
This effect happens when two variables are not perfectly correlated: if one picks a sample that has an extreme value for one variable, it tends to show a less extreme value for the other variable. For the Dunning–Kruger effect, the two variables are actual performance and self-assessed performance.
Is Google Making Us Stupid? What the Internet Is Doing to Our Brains! (alternatively Is Google Making Us Stoopid?) is a magazine article by technology writer Nicholas G. Carr, and is highly critical of the Internet's effect on cognition.
The cognitive reflection test (CRT) is a task designed to measure a person's tendency to override an incorrect "gut" response and engage in further reflection to find a correct answer; however, the validity of the assessment as a measure of "cognitive reflection" or "intuitive thinking" is under question.
In programming and software development, fuzzing or fuzz testing is an automated software testing technique that involves providing invalid, unexpected, or random data as inputs to a computer program. The program is then monitored for exceptions such as crashes, failing built-in code assertions, or potential memory leaks.
Moravec's paradox is the observation in artificial intelligence and robotics that, contrary to traditional assumptions, reasoning requires very little computation, but sensorimotor and perception skills require enormous computational resources. The principle was articulated by Hans Moravec, Rodney Brooks, Marvin Minsky and others in the 1980s.
