“In vain, therefore, should we pretend to determine any single event, or infer any cause or effect, without the assistance of observation and experience.”

Indeed, we must derive the relations of causality from experience; but we must not fail to correct and to complete our conception of these facts of experience by reflection.

Si toutes les parties de l’univers sont solidaires dans une certaine mesure, un phénomène quelconque ne sera pas l’effet d’une cause unique, mais la résultante de causes infiniment nombreuses ; il est, dit-on souvent, la conséquence de l’état de l’univers un instant auparavant.

Predictible Fakers (January 2009) http://www.overcomingbias.com/2009/01/predictible-fakers.html
Context: My experience is that journalists report on the nearest-cliche algorithm, which is extremely uninformative because there aren’t many cliches, the truth is often quite distant from any cliche, and the only thing you can infer about the actual event was that this was the closest cliche.... It is simply not possible to appreciate the sheer awfulness of mainstream media reporting until someone has actually reported on you. It is so much worse than you think.

The sad truth is that attractive people do better in school, where they receive more help, better grades, and less punishment; at work, where they are rewarded with higher pay, more prestigious jobs, and faster promotions; in finding mates, where they tend to be in control of the relationships and make most of the decisions; and among total strangers, who assume them to be interesting, honest, virtuous, and successful. After all, in fairy tales, the first stories most of us hear, the heroes are handsome, the heroines are beautiful, and the wicked sots are ugly. Children learn implicitly that good people are beautiful and bad people are ugly, and society restates that message in many subtle ways as they grow older. So perhaps it’s not surprising that handsome cadets at West Point achieve a higher rank by the time they graduate, or that a judge is more likely to give an attractive criminal a shorter sentence.
