Memes about the concept “Critical thinking”

101–111 of 111

Ann Druyan on the Humility of Science

I think that science tolerates the unknown in a way that religion doesn't. My argument is not with people who search for god. My argument is with people who feel that our understanding of god is completed. And those are the people who make so much of our existence on this planet such a hell, because they really think…

The Baloney Detection Kit

In science we may start with experimental results, data, observations, measurements, 'facts'. We invent, if we can, a rich array of possible explanations and systematically confront each explanation with the facts. In the course of their training, scientists are equipped with a baloney detection kit. The kit is…

Science is an Equal-Opportunity Critic

Again, the reason science works so well is partly that built-in error-correcting machinery. There are no forbidden questions in science, no matters too sensitive or delicate to be probed, no sacred truths. That openness to new ideas, combined with the most rigorous, sceptical scrutiny of all ideas, sifts the wheat…

Mistrust arguments from authority

One of the great commandments of science is, 'Mistrust arguments from authority'. (Scientists, being primates, and thus given to dominance hierarchies, of course do not always follow this commandment.) Too many such arguments have proved too painfully wrong. Authorities must prove their contentions like everybody…

The plural of anecdote is not data

A common way anecdotal evidence becomes unscientific is through fallacious reasoning such as the Post hoc ergo propter hoc fallacy, the human tendency to assume that if one event happens after another, then the first must be the cause of the second. Another fallacy involvesinductive reasoning. For instance, if an…

Facts We Learn as Children Aren't Supposed to Change

People who don't know a lot about science treasure what they do know, what they learned early as children, like: a) Eskimos have lots of words for snow. b) Wait 20 minutes after lunch before going swimming. c) There are nine planets, and the ninth one is Pluto. d) The biggest dinosaur ever was the Brontosaurus. e)…

When Science is Debated in the Courtroom

When Rachel Carson made us aware of the dangers arising from the mass application of toxic chemicals, she presented her arguments in the manner of an advocate, not a scientist. In other words, she selected the evidence to prove her case. The chemical industry, seeing its livelihood threatened by her action, responded…

CITOKATE

This is, in fact the critical discovery of science. That we often perceive what we expect or want to perceive, often at variance with what is objectively true. The Cro Magnon genius of trumping objective evidence with subjective belief. The original and only true form of magic. How has science dealt with this…

Can you stop thinking?

Can you stop thinking? Perhaps you have practiced meditation or some other method of calming the mind. If so you will know that the task is not trivial. If you have not, I suggest you try now to empty your mind for a minute or so (or if you cannot face it now, try it sometime when you have nothing 'better' to do…

The Importance of Time-Stamping to Relevance

Time-stamping is of interest because the temporal element of context is essential for understanding a text (to take an obvious example, when reading a paper on global geopolitics in 2006 it is essential to know whether it was written before or after 11th September, 2001). Furthermore, some information has a 'sell-by…
