17th Floor

After living in German House, Desmond, MacGregor E Entry, Pecker, Clam, Stickman, Floor Pi, Bonfire, and Black Mesa, the idea of taking an elevator to the place where I live is rather novel.

There’s actually some really wonderful things about up here, particularly the view. It’s awesome to live up high.

You can see quite a few of these things from here. And the roof of Westgate.

A Day with Sporcle, Revisited

Two months ago, I took 16 quizzes in each of ten categories in Sporcle and charted the results. It later dawned upon me that it would be probably more meaningful to chart percentiles (that is, percentile performance among those who took the quiz) rather than percentages, better accounting for difficulty variability in quizzes. (Now, it is more prudent to not skip multiple choice quizzes, for instance.)

So here’s this chart.

(Getting no answers is counted as 0th percentile and getting all answers is counted as 100th percentile for the purposes of this chart.)

And indeed, there’s quite a few transpositions. ‘Movies’ and ‘Sports’ swap positions, ‘Gaming’ moves down two columns, and ‘Language’ and ‘History’ swap. More interestingly, average percentile seems to now cluster into groups rather than being approximately evenly spaced from my worst category to my best category.

Buttons

You have a button. If you press the button, you have a 50% chance to win $500 and a 50% chance to lose $200. You don’t get to press the button more than once. Do you want to press the button?

You have a button. If you press the button, your friend has a 50% chance to win $500 and a 50% chance to lose $200. You don’t get to press the button more than once, and you don’t get to consult with your friend ahead of time about your friend’s opinion on what you should do. Do you want to press the button?

B is considering murdering C, and currently has a 50% chance of deciding to so. You have a button. If you press the button, with a 50% chance, B’s chance of deciding to murder C goes up to 80%, and with a 50% chance, B’s chance of deciding to murder C goes down to 5%. (Suppose, say, the button causes a video to be shown to B that alters B’s impression of C.) Do you want to press the button? If you press the button, and C ends up murdered, how much are you to blame for the fact that C is dead? If you do not press the button, and C ends up murdered, how much are you to blame for the fact that C is dead?

B is considering murdering C, and currently has a 50% chance of deciding to so. You have a button. If you press the button, with a 20% chance, B’s chance of deciding to murder C goes up to 100%, and with an 80% chance, B’s chance of deciding to murder C goes down to 0%. Do you want to press the button? If you press the button, and C ends up murdered, how much are you to blame for the fact that C is dead?

B is considering murdering C, and currently has a 2% chance of deciding to so. You have a button. If you press the button, with a 1% chance, B’s chance of deciding to murder C goes up to 100%, and with an 99% chance, B’s chance of deciding to murder C goes down to 0%. Do you want to press the button? If you press the button, and C ends up murdered, how much are you to blame for the fact that C is dead?

B is known to have a mental illness and is considering murdering C, and currently has a 50% chance of deciding to so. You have a button. If you press the button, with a 50% chance, B’s chance of deciding to murder C goes up to 80%, and with a 50% chance, B’s chance of deciding to murder C goes down to 5%. Do you want to press the button? If you press the button, and C ends up murdered, how much are you to blame for the fact that C is dead?

B is considering murdering C, and currently has a 50% chance of deciding to so. You have two buttons. If you press the first button, with a 50% chance, B’s chance of deciding to murder C goes up to 80%, and with a 50% chance, B’s chance of deciding to murder C goes down to 5%. If you press the second button, you defer this exact same choice to someone else, and you do not know who it is who is next presented this choice. Will you press either button, and if so, which one? If you press the first button, and C ends up murdered, how much are you to blame for the fact that C is dead? If you press the second button, and C ends up murdered, how much are you to blame for the fact that C is dead?
