The worst thought experiments imaginable – The Next Web

While the rest of us are doing good, honest work like podcasting and influencer-ing, theres a group of thinkers out there conducting horrific experiments. Theyre conjuring pedantic monsters, murdering innumerable cats, and putting humans inside of computers.

Sure, these thought experiments are all in their heads. But thats how it starts. First you dont know whether the cats dead or alive and then a demon opens the box and were all in the Matrix.

Unfortunately, there are only two ways to fight science and philosophy:

Thus, well arm ourselves with the collective knowledge of those whove gone before us (ahem, Google Scholar) and critique so snarky it could tank a Netflix Original. And well decide once-and-for-all whose big, bright ideas are the worst.

What if I told you there was a box that gave away a free lunch every time it was opened? Some of you are reading this and thinking is Neural suggesting we eat dead cats?

No. Im talking about a different box from a different thought experiment. Erwin Schrdingers cat actually came along some 68 years after James Clerk Maxwells Demon.

In Maxwells Demon, we have a box with a gate in the middle separating its contents (a bunch of particles) into two sides. Outside the box, theres what Maxwell calls a finite being (who other scientists later inexplicably decided was a demon) who acts as the gatekeeper.

So this demon being controls which particles go from one side of the box to the other. And, because particle behavior varies at different temperatures, this means the demons able to exploit physics to harness energy from the universes tendency towards entropy.

This particular thought experiment is awful. As in: its awfully good at being awesome!

Maxwells Demon has managed to stand the test of time and, a century-and-a-half later, its at the heart of the quantum computing industry. It might be the best scientific thought experiment ever.

The worst is actually Szilards Engine. But you have to go through Maxwells Demon to get there. Because in Szilards box, rather than Maxwells Demon exploiting the tendencies of the universe, the universe exploits Maxwells Demon.

Szilards work imagines a single-molecule engine inside of the box that results in a system where entropy works differently than it does in Maxwells experiment.

This difference in opinion over the efficacy of entropy caused a kerfuffle.

It all started when scientists came up with the second law of thermodynamics, which basically just says that if you drop an ice cube in a pot of boiling water, it wont make the water hotter.

Well, Maxwells Demon essentially says sure, but what if were talking about really tiny things experiencing somewhat quantum interactions? This made a lot of sense and has led to numerous breakthroughs in the field of quantum physics.

But then Szilard comes along and says, Oh yeah, what if the system only had one molecule and, like, the demon was really bored?

Those probably arent their exact words. Im, admittedly, guessing. The point is that Szilards Engine was tough to swallow back when he wrote it in 1929 and its only garnered more scrutiny since.

Dont just take my word for it. Its so awful that John D. Norton, a scientist from the department of history and philosophy of science at the University of Pittsburgh, once wrote an entire research paper describing it as the worst thought experiment.

In their criticism, Norton wrote:

In its capacity to engender mischief and confusion, Szilards thought experiment is unmatched. It is the worst thought experiment I know in science. Let me count the ways it has misled us.

Thats borderline hate-poetry and I love it. The only criticism I have to add is that its preposterous Szilard didnt reimagine the whole thing as Szilards Lizard.

The missed opportunity alone gets it our stamp for worst scientific thought experiment.

Honestly, Id say Ren Descartesscogito, ergo sum is the worst thought experiment of all time. But theres not much to discuss.

You ever meet someone who, if they started a sentence with I think, youd want to interrupt them to disagree? Imagine that, but at the multiverse level.

Accepting Descartesspremise requires two leaps of faith in just three words and Im not prepared to give anyone that much credit.

But, admittedly, thats low hanging fruit. So lets throw another twist in this article and discuss my favorite paper of all time because its also the worst philosophical thought experiment ever.

Nick BostromsSimulation Argument lies at the intersection of lazy physics and brilliant philosophy. Its like the Han Solo of thought experiments: you love itbecause its so simple, not in spite of it.

It goes like this: Uh, what if, like, we live inside a computer?

For the sake of fairness, this is how Bostrom puts it:

This paper argues that at least one of the following propositions is true: (1) the human species is very likely to go extinct before reaching a posthuman stage; (2) any posthuman civilization is extremely unlikely to run a significant number of simulations of their evolutionary history (or variations thereof); (3) we are almost certainly living in a computer simulation.

Think about it for a second.

Done? Good. It doesnt go any deeper. It really is just, what if all of this is just a dream? But instead of a dream, were digital entities in a computer simulation.

Its uh, kinda dumb, right?

But that doesnt mean Bostroms paper isnt important. I think its the most influential thought experiment since Descartess off-puttinginsistence upon his own existence (self involved much D?)

Bostroms a master philosopher because he understands that the core of explanation lies not in burdening a reader with unessential thought, but in stripping it away. He understands perfection as Antoine de Saint Exupry did when he declared it was attained not when there is nothing more to add, but when there is nothing more to remove.

Bostrom whittled the Simulation Argument down with Occams Razor until it became a paper capable of pre-empting your biggest yeah but, what about. queries before you could think them.

Still though, you dont have to be the head of Oxfords philosophy department to wonder if life is but a dream.

Theres no official name for this one, so well just call it That time the people building the A-bomb had to spend a few hours wondering if they were about to set the atmosphere on fire before deciding the math looked good and everything was going to be fine.

A close runner-up for this prize is That time the Nazis most famous quantum physicist was asked if it was possible that Germanys weapons could blow up the Earth by setting all the oceans aflame and he was all like: lol, maybe.

If I can channel our pal John D. Norton from above: these thought experiments are the worst. Allow me to list the ways I hate them.

The Axis and Allies werent far apart in their respective endeavors to create a weapon of mass destruction during World War II.

Of course we know how things played out: the Germans never got there and the US managed to avoid lighting the planet on fire when it dropped atomic bombs on the civilian populations of Hiroshima and Nagasaki.

In reality, Albert Einstein and company on the Allies side and Warner Heisenberg and his crew on the Axis were never concerned with setting off a globally-catastrophic chain reaction by detonating an atomic bomb. Both sides had done the math and determined it wasnt really a problem.

Unfortunately, the reason were aware of this is because both sides were also keen to talk to outsiders. Heisenberg famously joked about it to a German politician; Arthur Compton, whod worked with Einstein and others on The Manhattan Project, gave a now infamous interview wherein he made it seem like the possibility of such a tragic event was far greater than it actually was.

This is our selection for the absolute worst thought experiment(s) of all time because its clear that both the Axis and the Allies were pretty far along in the process of actually building atomic bombs before anyone stopped and thought hey guys, are we going to blow up the planet if we do this?

Thats Day One stuff right there. Thats a question you should have to answer during orientation. You dont start building a literal atom bomb and then hold an all-hands meeting to dig into the whole killing all life thing.

Those are all great examples of terrible thought experiments. For scientists and philosophers anyway. But everyone knows the worst ideascome from journalists.

I think I can come up with a terrible thought experiment thatll trump each of the above. All I have to do is reverse-engineer someone elses work and restate it with added nonsense (hey, it worked for Szilard right?).

So lets do this. The most important part of any thought experiment is its title. We need to combine the name of an important scientist with a science-y creature if we want to be taken seriously like Maxwell and his Demon or Schrdinger and his Cat.

And, while substance isnt really what were going for here, we still need a real problem that remains unsolved, can be addressed with a vapid premise, and is accessible to intellects of any level.

Thus, without further ado, I present: Ogres Ogre, athought experiment that uses all the best ideas from the dumb ones mentioned above but contains none of their weaknesses (such as math and the scientific method).

Unlike those theories, Ogres Ogre doesnt require you to understand or know anything. Its just quietly cajoling you into a natural state of curiosity.

In short, Ogres Ogre isnt some overeager overachiever like those others. Where Maxwells Demon demonizes particles by maximizing the tendency toward entropy, and Szilars Engine engages in entropy in only isolated incidents, Ogres Ogre egregiously accepts all eventualities.

It goes like this: What if C-A-T really spelled dog?
