As you might have gathered from the fact that people aren't pulling that prank all the time, there is no drug that will let you fake your death. If you take tetrodotoxin at a low enough dose, you just get a tingling or analgesic effect. If you take more than that, at best you'll end up in a deep coma, but it ain't fooling any modern doctors ... which is a good thing, because you'll need their assistance to survive in that state. It's not like this thing can magically make it so you don't need to eat or breathe for days.

The level of detail is so uncanny that it allows the main character in Psych to regularly fool people into thinking he has magic powers ... but this is totally a real thing, right? Nope, not really. In decades and decades of studies and research, scientists have only been able to find one person with anything resembling Hollywood's idea of a "photographic memory," and it was in less than ideal circumstances (she married the scientist who found her and he stopped studying her, presumably because he was tired of losing every argument).

Now, there is something called eidetic memory, but it's not the same thing -- eidetic images only last for several minutes at most, and can sometimes be destroyed just by blinking. It isn't really a photograph so much as it is a chemically unstable Polaroid. On top that, they're not really that accurate. The Bourne movies apparently omitted all the scenes of Damon stopping his chases to ask for directions.

And that's leaving out the fact that just because a person has an excellent visual memory, it doesn't mean they're some kind of perfect memory god. We humans have many different kinds of memory, it turns out. That's partially why Tatiana Cooley, multiple-year-winner of the Memoriad World Mental Olympics, still needs to use Post-it notes and shopping lists to remind her of simple everyday things (a statement so ironic that we don't blame you for clicking the link to check it).

In case you aren't familiar with this article's premise by now: That's not a thing that exists. First of all, poisoning isn't an exact tactic: Different people respond to different substances ... well, differently. One of the reasons people survive poisoning attempts is that there's no universal dosage that works on everyone; it's not like the killer can get you to try different things and adjust accordingly, like he's your psychiatrist. Another reason is that we actually have lots of antidotes for poisons -- here's one for freaking cyanide.

James Bond's entire medicine kit is just six of these and twelve gonorrhea shots.

Poisoning is actually a really easy way ... to draw attention. That's something that this guy convicted of killing his wife with an "untraceable" poison found out firsthand. Not only are you leaving some kind of purchase trail, but almost every poison has symptoms (and potential suspects) so obvious it's like printing a crossword right next to its answer key. They're hardly the stealthy killers spy films portray them as. Cyanide, for instance, gives its victims the shakes and a red flush, and arsenic makes people vomit and s**t themselves (which Christie mercifully left implied).

Long story short, there's no poison that matches all the descriptions we listed above. We guess the takeaway is this: If you're planning to poison someone, just mute them on Twitter instead.

Nootropics might one day reach a stage where they enhance our cognition, but right now we don't even know if that's possible, since there's very little serious research on this field. Also, a lot of these drugs are actually "supplements," which means they're a lot less regulated ... which, in turn, means the companies can fill them with a bunch of substances that don't actually do anything and charge you money for the picture of a glowing brain on the bottle.

The harsh truth is that there's rarely a secret shortcut to being spies, or writers, or stock market experts. Just an eager mind and hard work. (So yeah, you're never finishing that book.)

The notion that we have violent tendencies lurking inside us and that we can "cool off" once we have expressed them is called catharsis theory, and it's everywhere from The Purge to tortured justifications for supporting high school football. How many times were we told, as children, to punch pillows to let off some steam? Basically, by letting out our inner Joe Pesci every once in a while, we prevent ourselves from being all Pesci, all the time.

The one problem with this theory is that once researchers started testing it, they realized that the exact opposite was true. As we have mentioned once or twice, unleashing your anger to "blow off steam" actually leaves you angrier. In fact, the better you feel after venting, the angrier you are, because you've just spent all that time wallowing in it. And that's why you know basically no one who turns into a raging a*****e only once a year and has perfect control of his emotions the rest of the time.

Believe it or not, this guy is most likely a dick in his regular life, too.

The solution to anger and violent impulses isn't to indulge in them like a guilty-pleasure chocolate bar: it's to calm the hell down by watching ASMR videos or listening to that one CD of ocean sounds you got for Christmas for some reason. So if you're one of those internet people asking, seriously or otherwise, whether we should make the Purge a reality: No. Duh.

Brainwashing first entered American consciousness as we began to be concerned about communism. Why would American POWs collaborate with the enemy and make false confessions? The Reds must have some secret technique capable of forcibly converting them! It was horrifying and inhuman ... and naturally, the CIA decided to get in on this action with the MKUltra mind control project (and its lesser known, sex-obsessed cousin). When the Unification Church became a thing in America, parents believed their children joined because they were brainwashed, and paid lots of money to have them be "deprogrammed." This hysteria eventually subsided, but the idea of brainwashing stuck around -- it's still a common trope in everything from comics to games to cartoons to pro wrestling.

Examples in increasing order of ridiculousness.

Sure, it is possible to persuade some people to do something through extreme peer pressure and such, but somehow we don't think the CIA was worried about Americans being told that all the cool kids were trying communism. The truth is that brainwashing as we understand it doesn't exist. Like most endeavors that involve buying a shitload of drugs, the CIA ended up declaring MKUltra a failure -- the very head of the project eventually declared it useless. It turns out that all those Commie-captured POWs we were worried about were just the victims of traditional techniques, and, once free, stayed "converted" for about as long as the McRib's annual appearance in America.

The American Psychological Association later reached the same conclusion about the Unification Church and other such movements: they aren't capable of brainwashing people, which probably explains why there's not many of them. Coercing them, maybe, but that's different. The church's persuasive powers were about on the level of multilevel marketing or dancing street gangs.
