Answer: Placebo effect
John is experiencing placebo
effect where the pill that contains no pain killing medication has given pain
relief to John. A placebo is a substance with no therapeutic effect but sometimes
improves patient’s condition. This is due to patient’s expectation that the
pill they take can help or ease the pain they have even if no active ingredient
is present.
Therefore, the effect is more
than positive thinking or believing that a treatment will work by creating a
stronger connection between the brain and body as they work together.
