Libertarianism secretly relies on most individuals being prosocial enough to tip at a restaurant they won't ever visit again.

I'm puzzled that you gave that specific example, given that it's obviously wrong. Most countries do not have a culture of tipping, and their economies don't implode. They just have less headaches at bill time. And in many cases (a long way from libertarianism) their wait staff get paid a living wage.

I'm also not sure what it means for libertarianism to rely on something, since libertarianism is not an actual functioning thing in existence. But if it did exist and function, it would not rely on tipping.

When you pick up a cup of water... the force exerted by your hand must be zero.

Unless you are holding the cup up, supporting it against the force of gravity.

This shouldn't be down-voted if for no other reason then it shows that a regular contributor to LW got an article in a major paper that contains the following paragraph:

"Recent research shows that after any emotionally powerful event, our brains tend to assign too much weight to that event compared with what is really important to us, a thinking error called attentional bias. To fight this thinking error, we should consider what are our actual goals and how best to reach them."

THESE DETAILS ARE INCORRECT. I'm trying to get this event deleted.

You should see a "edit meetup" link underneath the map at that link.

You should be able to edit it here: http://lesswrong.com/meetups/1ke (not from the discussion article).

There's a small 'edit meetup' link below the map.

Can I edit events that I created on Less Wrong?

It seems I can't. (I ask because I created this event, but when I pasted the details, I neglected to add the city (Melbourne). And now the map is wrong by about 3600km.

MELBOURNE! I forgot to write Melbourne, and the map incorrectly shows Perth. It seems I can't edit an event that I created.

When I write a character, e.g. Draco Malfoy, I don't just extrapolate their mind, I extrapolate the surrounding subjective world they live in, which has that character at the center; all other things seem important, or are considered at all, in relation to how important they are to that character. Most other books are never told from more than one character's viewpoint, but if they are, it's strange how often the other characters seem to be living inside the protagonist's universe and to think mostly about things that are important to the main protagonist. In HPMOR, when you enter Draco Malfoy's viewpoint, you are plunged into Draco Malfoy's subjective universe, in which Death Eaters have reasons for everything they do and Dumbledore is an exogenous reasonless evil.

This is an awesome trick, and I'll have to use it more explicitly when writing various characters. (I already did somewhat, but I'm not sure if I've explicitly thought of it in these terms.)

"grass is green" and "sky is blue" are always funny examples to me, since whenever I hear them I go check, and they're usually not true. Right now from my window, I can see brown grass and a white/gray sky.

So they're especially good examples, as people will actually use them as paradigms of indisputably true empirical propositions, and even those seem almost always to be a mismatch between the map and the territory.
