I think the joke of the ghost costume as a white sheet has been lost.

and what’s the deal with airplane food!?

The ones that would stick around would likely be very racist. Consider that you don’t even need to stay in earth, you can just travel the universe. Or just travel the world. You don’t have gravity to help you, but passing thru solid matter isn’t a problem either. You could check out the core, Iceland, Botswana, Jordan, Kentucky, whatever. So if they stay in Kentucky, they’re gonna be super racist. But evidently not…

Ghosts are the creation of our minds. And it turns out that our minds are flawed machines. This was shown by someone and they won a Nobel Prize for it (Daniel Kahnemann). If we understand our flawed minds, we understand why ghosts aren’t racist.

When you think of something, you run a simplified simulation of it. When you run these simulations, you don’t think about other things. For example, when people fantasize about achieving something, they usually run the simulation of having gotten the job and the money or having solved the tough problem. However, they usually don’t think about the path to achieving that goal. This is called the planning fallacy. It’s also called the Motivation Wave in Behavior Design.

Another example of these simplified simulations is the halo effect. The halo effect starts when you notice something good about someone. Maybe they’re attractive. Maybe they’re on your same team or political group or religion or whatever. The thing is that you end up building a good preconception of that person. You assume they’re kind and smart and many other positive things. Again, your mind is running a simplified simulation. Even if you notice bad stuff about the other person, you may ignore it because our mind is a flawed machine and it’s stuck with the idea that the other person is good.

So, how do simplified simulations lead to non-racist ghosts? Well, we all share an idea of what a ghost is. We tell each other ghost stories or we watch movies with ghosts in them. All of that feeds the simplified simulations we run when we think of ghosts. And we don’t include racism in those simulations.

This doesn’t mean that we can’t escape simplified simulations. This is a tough problem that many people have tried to solve in many different ways. These attempts have resulted in an arsenal of methods: psychological flexibility exercises, mental contrasting, pre-mortems, the Delphi method, red team blue team exercises, weak signal detection, etc. Notice that all of these tools try to transform our preconceptions.

Of course, a very simple way of transforming our preconceptions is to prove them wrong. I suppose in the case of non-racist ghosts, it’s a matter of creating racist ghosts. This project, however, brings up the old adage: just because you can doesn’t mean you should.

If you’re interested in simplified simulations, I recommend Lisa Feldman Barret’s books. You can also check out Daniel Kahnemann, Gary Klein, and Dave Snowden.

I like to think they observe and change with the times. Kind of grow in death.
