Did you know you placebos can be addictive or that they work best if they’re expensive and have a brand name? Some placebos work in Germany but not in the rest of Europe while others will make Americans feel better but will have no effect on Australians. A placebo in pill form is not as effective as if it’s administered as a capsule and that’s not as powerful as an injection or surgery. If the placebo involves a big machine that goes ping it can be the most effective of all. But, not all placebos work on everyone and even the color of a placebo can have an upper (red) or a downer (blue) effect.
