It's worth remembering - especially as reporting verges on the
hysterical at times - the placebo effect is very, very real.


/nocebo/ effect?

Well nocebo happens when you *know* the substance you are taking is a
sugar pill.

Placebo is when it's the real thing - or you believe it is.

No. The placebo effect is additional good effects from believing that
the medicine (real or not) will do good. The Nocebo effect is additional
bad effects from believing that the medicine (real or not) will have
side-effects.
