Dragonfly is the one I’m most excited about.

Seeing liquid bodies on another world would be amazing.

It gets even more interesting. People have mentioned the nocebo effect.

The placebo effect can backfire. Australian science popularizer Dr Karl talks about when he was on duty in a hospital he had to give a saline solution in lieu of morphine to a patient in pain. He told the patient he was giving him something to combat the pain. When the saliva solution was injected the patient’s pain went away as though he was actually given morphine.

The nurse wasn’t surprised by this and told Dr Karl to make sure they treat this medically as a morphine injection and time the next one as such since I’d they immediately gave him a real morphine injection he would OD.
