There's also the theory of song enough induction.

I'm going to mangle the description, but it says,

if you want to find a theory that explains

why something is happening.

And now a theory here is something that's encoded

as a binary string.

Then the correct theory is actually

going to be a probability weighted theory that takes

to account all the possible theories,

but weighs them based on their complexity.

So the simpler ones are more likely to be true

and the more complex ones are less likely to be true.

And you sum them all together,

and that's how you figure out the correct probability

distribution function for your explanation.

That's similar to Bayesianism, isn't it?

In both cases, they're assuming that you can enumerate

all the possible theories, but you can't,

because that's the creativity coming in.

It's very rare in science to have more than one viable theory.

In physics, we mentioned Newtonian theory of gravity,

and there was general relativity.
