Criticism
There is no peer reviewed scientific evidence that crystal healing has any effect. It has been called a pseudoscience. Pleasant feelings or seeming successes of crystal healing can be attributed to the placebo effect, or the believers wanting it to be true and seeing only things that back that up; cognitive bias.
Crystal healing techniques are also practiced on animals, although some veterinary organizations, such as the British Veterinary Association, have warned that these methods are not scientifically proven and thus could cause greater harm if not used in conjunction with traditional medical care.

Famous quotes containing the word criticism:
“The aim of all commentary on art now should be to make works of art—and, by analogy, our own experience—more, rather than less, real to us. The function of criticism should be to show how it is what it is, even that it is what it is, rather than to show what it means.”
—Susan Sontag (b. 1933)
“A bad short story or novel or poem leaves one comparatively calm because it does not exist, unless it gets a fake prestige through being mistaken for good work. It is essentially negative, it is something that has not come through. But over bad criticism one has a sense of real calamity.”
—Rebecca West (1892–1983)
“Parents sometimes feel that if they don’t criticize their child, their child will never learn. Criticism doesn’t make people want to change; it makes them defensive.”
—Laurence Steinberg (20th century)
