  • Yeah I was more pointing out the ridiculousness of the GOP than trying to legitimize GWAR as serious political commentary :)

    Fun fact: they’ve been doing this forever. I saw them in 92 just after Perot joined the race. They only had dummies for Clinton and Bush so they had to scramble to mock up a Perot dummy from spare parts for the show, for which they apologized beforehand. GWAR cares about quality!

  • Nitrogen is almost 80% of air so it’s hardly in short supply. Also why would you need medical grade? This is like alcohol swabs at the IV insertion site for lethal injection. They just don’t want the bad publicity of being associated, but it’s not going to stop anything.

  • Have you ever met a martial arts dude who wasn’t also into guns? :)

    I’m sure he’s putting in plenty of time on the range too, but that doesn’t make for as good a publicity campaign.

    I’ve also heard other strategies discussed, like deadman switches and explosive collars. I’m sure they have plans within plans.

  • Thanks!

    We had to learn altruism to survive the neglect, so our parents accidentally trained us not to pull up the ladder like the Boomers. Lord of the Flies debunked.

    To be honest the neglect was better than when they did pay attention, for all we complain about it. No parenting was better than shitty parenting.

  • My pleasure, I’m always down for nerding out on stuff like this.

    Another fun example of the early visual processing is feature detection. The parallel processing allows us to instantly find a green square in a sea of red squares, as it jumps out at you.

    But when you combine multiple independent features together (find the green square in a sea of red and green squares and circles) now we have to tediously look around the whole image. That integration of multiple features forces the work higher up in the visual system and takes more time, attention, and effort. Thats why Where’s Waldo is hard.

  • Psychophysics is the study of the relationship between stimuli and perception. A lot of it is perceptual thresholds, so how much sound or light is needed for someone to hear or see something (fun fact: people can reliably detect a single photon in a dark room at better than chance). Thus much of the experimental protocols boil down to asking “can you hear this?” after playing a sound which is what the Verizon ads always made me think of.

    The other half of the discipline is figuring out the wiring on low level perception. For instance we have massive parallel processing in the early visual system that does things like highlight lines and edges, which is what makes the Mach dot/band illusions work:

    It’s what I studied in undergrad as it was a nice overlap in my interests in cognitive science, psychology and computer science. I basically just like knowing how everything works :)
