Cops would have been 100% justified in shooting gelman at any point after he started swinging his knife towards the narrator and before the narrator disarmed him.. Or at least kicking the shit out of him as necessary to stop his killing spree. Due process is for after the perp has been apprehended.

@SDGundamX you're confusing psychopathy with insanity. Lots of psychopaths are perfectly sane. Being a psychopath vastly increases the likelihood of committing murder. And it's heritable. And it's a continuum. But it's rare enough to be a relatively minor cause of murder rates. In place of "genes for psychopathy" I should have said "genes for anything that predisposes one to commit murder".

First degree murder is less than 10% of all murder. Most murders are spur of the moment. Having a higher IQ correlates with doing better on the marshmellow test and having greater impulse control to avoid spur of the moment destructive behavior. IQ is a vastly better predictor of criminality than parental SES ( http://akarlin.com/wp-content/uploads/2012/08/bell-curve-crime-iq.jpg ) Japanese have 7 points higher average IQ than the US. IQ is >50% heritable.

@SDGundamX those cultural factors are all true, and none of it contradicts my point. Both culture and inborn personality traits play a role. A place where murderers have been routinely caught and removed from the gene pool for centuries is going to be a place with a lot less genes for psychopathy. Not so much in a frontier society without effective law enforcement for much of its history, like the US. The US isn't the worst in this respect, but it hasn't been civilized for nearly as long as Western Europe or Japan, and this is a source of both genetic and cultural differences.

Even the non-firearm homicide rate in the US is 5 times that of Japan. Japanese gun control can't take credit for all that. Personality is more than 50% heritable, and by extension, so is violent behavior. (Case in point: the vegas killer's father was on the FBI most wanted list). Personalitywise, Japanese tend to be relatively meek and inhibited. Even if every one of them owned a gun, their murder rate would probably still be a fraction of the US murder rate.

1. Mass shootings are <1% of the murder rate, and murder is <1% of the death rate. Getting wound up about mass shootings is as dumb as getting wound up about terrorism. They're both very small in relation to how much people freak out.
2. We already have lots of gun control. Especially in places like California, where the killer bought most of his guns legally and passed a background check.

3. Bump stocks were the real problem. Even the NRA is open to restricting bump stocks. Let's do that.

4. Let's not go overboard with the Australian solution. Australia's murder rate almost halved from 1990 to 2015, and people erroneously give the buyback credit for that, but in that same 25 year time span the US murder rate went down even more (from 9.4 to 4.5 per 100,000) The murder rate went down everywhere in that time frame due to banning leaded gasoline that causes brain damage. Also due to some smaller factors (more abortion, better software for predictive policing).

This will only work if the canoe is made of a material lighter than water.

In dogs, artificial selection gave lots of variety that couldn't have existed in nature. But in humans there's no distinction between natural selection and artificial selection. We intelligently select our own mates by stringent criteria. Females favor good providers, and the cognitive traits that make a good provider changed drastically over the past 10,000 years, so you would expect the frequencies of genes affecting cognition to undergo unusually rapid change.

Counterpoint to Yogi's "never give up": http://freakonomics.com/2011/09/30/new-freakonomics-radio-podcast-the-upside-of-quitting/

Seconding Artician. The brain evolved by natural selection, just like the rest of the body. It has built in biases and modules that vary genetically. Look at the wide variety of personalities in dog breeds, for example. In humans, the big five personality traits are estimated to be about 50% heritable based on twin studies.

Gattaca is a good movie and Brave New World is a good book, but they should not be taken as the ends of some slippery slope that any eugenic policy inevitably leads to. I think it's unfortunate that so much fear of eugenics is propagated by dystopian fictions like those. Eugenics can be done in a humane way that respects all individual rights. For instance:

1. a system of incentives for highly successful people to have more children or donate to sperm banks.

2. Universal single-payer healthcare, providing among other things free condoms and birth control pills to all, so that the use of contraception will not be so much inversely correlated with income as it has been from 1850 to the present when the poor often couldn't afford it (and it's a demonstrable fact that on average the poor tend to have lower intelligence partly due to genetics)

Even such modest, individual rights respecting policies, if phrased in terms of benefiting the gene pool, are political suicide because people are still afraid of imaginary slippery slopes leading to Hitler. Most of the US is still in denial of the implications of biological science, for reasons that speak well of them, but it's time to grow up and get over that habit of Godwinizing any attempt to improve the gene pool regardless of whether it infringes individual rights.

Or maybe lots of people people don't actually believe that, but are reluctant to say otherwise: https://www.youtube.com/watch?v=B0W9sSqeJnA

Haven't read the books yet but I hear he survives somehow, so I'll bet that Jaime helps him escape, because that would help set up conflict between Jaime and Circe.
