The Man Behind the Pill Decided Women 'Need' to Have Periods—But They Don't - Broadly
If you're on the birth control pill, you're most likely going through withdrawal bleeding once a month. But there's no medical reason for having a simulated period every three weeks.

What if the Placebo Effect Isn’t a Trick? - The New York Times
New research is zeroing in on a biochemical basis for the placebo effect — possibly opening a Pandora’s box for Western medicine.

Genetic information as self-fulfilling prophecy
La informació genètica pot exercir un potent efecte placebo… o nocebo. En aquest experiment realitzat a Stanford, s'analitzava l'ADN dels subjectes participants i tot seguit se'ls informava sobre la seva capacitat innata per a fer exercici físic i sobre el seu risc d'obesitat. En l'hora següent, es va comprovar que els afavorits per la loteria del genotip podien córrer més temps que abans o s'atipaven més ràpid, al contrari que els seus companys; <em>independentment que a uns o a altres se'ls hagués dit la veritat o se'ls hagués mentit</em>. “Els psicòlegs que van dirigir aquest estudi no saben per què van trobar el que van trobar. Tot i que la informació genètica pot canviar el comportament, no pot explicar els canvis fisiològics tan ràpids que hi van veure. L'estrès tampoc ho explica, ja que la percepció d'un genotip protector va generar un augment fisiològic de les hormones que controlen la nostra alimentació. Conclouen que el mecanisme causal, que té efecte instantàniament, és la «mentalitat» [<em>mindset</em>].”

What if the Placebo Effect Isn’t a Trick?
Kaptchuk, who before joining Harvard had been an acupuncturist in private practice, wasn’t particularly disturbed by the finding that his own profession worked even when needles were not actually inserted; he’d never thought that placebo treatments were fake medicine. He was more interested in how the strength of the treatment varied with the quality and quantity of interaction between the healer and the patient — the drama, in other words.


It is not possible to assay levels of COMT directly in a living brain, but there is a snippet of the genome called rs4680 that governs the production of the enzyme, and that varies from one person to another: One variant predicts low levels of COMT, while another predicts high levels. When Hall analyzed the I.B.S. patients’ DNA, she found a distinct trend. Those with the high-COMT variant had the weakest placebo responses, and those with the opposite variant had the strongest. These effects were compounded by the amount of interaction each patient got: For instance, low-COMT, high-interaction patients fared best of all, but the low-COMT subjects who were placed in the no-treatment group did worse than the other genotypes in that group. They were, in other words, more sensitive to the impact of the relationship with the healer.

What if the Placebo Effect Isn’t a Trick? - The New York Times
the placebo effect is a biological response to an act of caring; that somehow the encounter itself calls forth healing and that the more intense and focused it is, the more healing it evokes.
“caring in the context of hope qualitatively changes clinical outcomes.”
