Is It Science or Pseudoscience?

Pseudoscience (su doh-science)

Beliefs or practices that are mistakenly believed to be based on the scientific method (but are NOT)

Scientific Method: ObservationHypothesisExperimentDataConclusionRepeatable!!!

Pseudoscienceis like bubble gum. It tastes pretty good, its fun to blow bubbles, and it annoys some people. But eventually, the flavor leaves, and you find that youre just chewing on some nutritionally dubious substance. Now you have to find a place to spit it out.

End Result of Believing Pseudoscience

Evidence of Pseudoscience: Your own Pseudoscience DetectorThe discoverer pitches his claim directly to the media. Going to media directly bypasses the all-important peer-review process, where real scientists can evaluate whether the claim is real science.Evidence of Pseudoscience: Your own Pseudoscience DetectorThe discoverer says that a powerful establishment is trying to suppress his/her work.If the powerful establishment really thought the work was valid, they would be trying to make a profit off of it.Evidence of Pseudoscience: Your own Pseudoscience Detector3. The scientific effect is always at the very limit of detection.

This is the very definition of it doesnt work.Evidence of Pseudoscience: Your own Pseudoscience Detector4. Evidence for a discovery is anecdotal (personal stories).

Anecdotes are not data. More anecdotes are not data. Anecdotes are not controlled, but they are subject to all sorts of bias, such as the observer only picks anecdotes that support their belief. The problem with that is we have no idea if the anecdote is, in fact, accurate; and we ignore all the data that does not support the anecdote.Evidence of Pseudoscience: Your own Pseudoscience Detector5. The discoverer says it is credible because it has endured for centuries.

Just because its been around for a long time, doesnt mean its credible. (Remember, for centuries people thought that the world was flat.)Evidence of Pseudoscience: Your own Pseudoscience Detector6. Discoverer has worked in isolation.Science is a collaborative effort, because new ideas need to be subjected to the bright lights of criticism and review. If the new discovery is truly groundbreaking, others will need to repeat it and publish about it, so that unbiased observers can add the new information into the wealth of science.Evidence of Pseudoscience: Your own Pseudoscience Detector7. The discoverer must propose new laws of nature to explain an observation.

New laws of nature are developed over time through scientific consensus, not through the proclamation of a single scientist.your TaskResearch one of these topics online.
