If you want to maximize your expected utility, you try to save the world and the future of intergalactic civilization instead of donating your money to the society for curing rare diseases and cute puppies.

If you've been cryocrastinating, putting off signing up for cryonics "until later", don't think that you've "gotten away with it so far". Many worlds, remember?

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.

"Gryffindors," spat Professor McGonagall, the word carrying a freight of bitterness and despair that fell like an eternal curse on all youthful heroism and high spirits.

A burning itch to know is higher than a solemn vow to pursue truth. To feel the burning itch of curiosity requires both that you be ignorant, and that you desire to relinquish your ignorance.
