Here’s an interesting study we could do.

Is there a placebo effect for car repair. And how does it compare to human “repair”?

You could pretend to fix peoples car issues and see if they report it improving.

Assuming the mind can’t fix cars mentally it would let you isolate what part of the placebo effect is perception.

Discuss..

There are devices that plug in to the OBD2 or cigarette lighter charging port & claim to boost power or MPG, but in reality only light up an LED. I think some people are fooled into thinking they work by wishful thinking, expected result bias, etc., so I'd expect we could find evidence for particular kinds of placebo effect among some people WRT cars
