The Best Textbooks on Every Subject

For years, my self-education was stupid and wasteful. I learned by consuming blog posts, Wikipedia articles, classic texts, podcast episodes, popular books, video lectures, peer-reviewed papers, Teaching Company courses, and Cliff's Notes. How inefficient!

I've since discovered that textbooks are usually the quickest and best way to learn new material. That's what they are designed to be, after all. Less Wrong has often recommended the "read textbooks!" method. Make progress by accumulation, not random walks.

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 response to science denial is not just more science. We stop science denial by exposing people to a weak form of science denial. We need to inoculate minds against misinformation.

The practical application of inoculation theory is already happening in classrooms, with educators adopting the teaching approach of misconception-based learning (also known as agnotology-based learning or refutational teaching).

This involves teaching science by debunking misconceptions about the science. This approach results in significantly higher learning gains than customary lectures that simply teach the science.

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
