Feinne posted:I'd also imagine if you believe they work it'll tend to stress you out more when you're lying while connected to one and maybe sort of make it work (I was about to compare it to voodoo in in the previous post since it mostly works if you think it works). The theory behind them is that lying should produce certain measurable differences in things like blood pressure, sweating, and heart rate. It sounds good because a lot of people do get nervous when they decide to lie but typically try to hide it. Some people are obviously better liars than others but in theory you should be able to measure a physical change whenever somebody lies. A major snag comes from the fact that other things can make a person nervous and affect those numbers. I imagine being locked in a room with multiple armed police officers is not a stress-free thing especially when they're interrogating you. If you're measuring, say, heart rate then a polygraph operator or the team around could do something deliberately to make your heart rate spike and go "well you said you were not guilty but this spike here indicates that this was a lie so..." It sounds good but the snag is that polygraph operators claim to have a greater than 90% accuracy which has never, ever been actually demonstrated. They were invented in the 1920's and have since been completely unproven which of course means they aren't scientific at all. Forensics actually has similar issues; some popular forensic techniques have since been debunked to gently caress and back but TV shows love them because they allow something as complex as a crime investigation to be wrapped up neatly in an hour with a total slam dunk. It isn't that the polygraph is easily fooled it's that it's straight up bullshit in the first place. Even the guy that invented the thing admitted that reading the output data involved a lot of interpretation and intuition rather than actual scientific measurement. That right there makes it not pass the smell test. The fact that no polygraph operator has ever managed to provably get anywhere near the claimed 90% accuracy just makes it worse.

Yeah, that's what I was trying to get at by noting that the case where you'd want to use them is also where they're pretty much just total nonsense, since as you note there's way too much confounding stress. And again as you note, they're just reading tea leaves end of the day.

I like the scene in The Wire (I think?) where they ask the polygraph tech what the results are and he's like " that's not how this works, tell me what you want the report to say".

We get FTL with this level of civilization, we're gonna be the IRL Ferengis of the galaxy. "Oh Glorphanuljixplan, here comes some humans to sell us more of their cheap poo poo, shut down the comms." We'll be the guys offering to asphalt your driveway of the Milky Way, the species blasting down the star lanes crapping out advertising on every frequency.

This is both a serious potential issue but also one that has a lot of serious effort being put into it. The main difficulty is avoiding putting something up there that can contribute to the problem it's attempting to solve.

FilthyImp posted:You basically have to drag it so it burns up or crashes, because otherwise you're just making dozens of Gravity-like hellparticles right? I think technically the issue is that trash stuck in orbit is "falling" "very fast" in a way where its stuck in orbit for a long time; so you what you actually want to do is slow it down so it's orbit actually decays and then burns up etc. You got big stuff like discarded rocket stages which are big enough you could probably just harpoon it; but this risks spalling which we might want to avoid hence the laser suggestion to decay its orbit. For smaller stuff the idea is to presumably try to vaporize the smaller stuff, slow it down with the energy imparted to it, or catch it with a strong net.
