La peligrosa idea de la igualdad entre ciencia y opinión

A lo que asistimos hoy en día es a la inversión de este esquema: al desprestigio de la episteme o ciencia a favor de la doxa u opinión y a la igualación de ambas como meros gustos o preferencias. Esta inversión se ha producido por un proceso en tres pasos. En primer lugar, se ha eliminado la propia diferencia: los juicios científicos acerca de la realidad se han transmutado en opiniones científicas, pero opiniones al lado de las opiniones no científicas. En un segundo paso, se igualan ambas: se ignora lo de “científicas” y pasan a ser opiniones sin más como las otras. En un tercer paso, se equipara la opinión al gusto. Cada uno tiene una opinión como tiene un gusto: opino tal cosa porque me gusta esa opinión. El caso es que ahora ya no hay diferencia entre una y otra, la opinión científica y la no científica valen exactamente lo mismo: en función del gusto de cada uno.

“Doctor,” said Sacha, “Can you give me your assurance that this injection won't harm my children?”

“Well, there's always some risk, Ms Melham. I do have a leaflet that explains everything...”

Sacha placed a finger on the table.

“I don't need a leaflet, Doctor. I simply want your assurance that this injection will cause Willow and Gregory no harm...”

Doctor James Ferriday gazed at the finger.

“As I said, there is always a small risk, but if you look, you will see that this is less than the probability of...”

Sacha held up her hand.

“Please, Doctor. Don't try and confuse the issue.”

“I'm not trying to confuse the issue, I'm simply presenting you with the facts...”

The bias blind spot is the cognitive bias of recognizing the impact of biases on the judgement of others, while failing to see the impact of biases on one's own judgement.

Emily Pronin and Matthew Kugler have argued that this phenomenon is due to the introspection illusion, a cognitive bias in which people wrongly think they have direct insight into the origins of their mental states, while treating others' introspections as unreliable. http://en.wikipedia.org/wiki/Introspection_illusion

Typologies of Extreme Longevity Myths

Age claims of 110+ years and the age validation experiences of the authors facilitated a list of typologies of false age claims. Results. Invalid age claim rates increase with age from 65% at age 110-111 to 98% by age 115 to 100% for 120+ years.
Purpose. Political, national, religious, and other motivations have led the media and even scientists to errantly accept extreme longevity claims prima facie. We describe various causes of false claims of extraordinary longevity. Design and Methods. ...

The science of why you really should listen to science and experts

This research does not mean that experts have no reasoning flaws. It just means they seem to be able to put their own personal, political identities to the side when engaging in reasoning in realms where they’re highly trained. “Experts can be demonstrated to be vulnerable to foreseeable forms of cognitive biases — including confirmation bias & the like —  under one or another set of circumstances even if in general they aren’t vulnerable to identity-protective cognition,”
All humans are biased. But some humans are less biased than others.
