Explanation:
When a researcher accidentally influences how participants behave, this effect is referred to as placebo effect
<h3>
What is placebo effect?</h3>
The placebo effect occurs when a patient receives a "dummy" treatment such as a placebo and their physical and mental health improves as a result.
In a placebo effect, the patient only reacts to the treatment because they think it is having an impact on them.
Much like when you give a youngster sugar tablets to take the edge off of their agony, they take them like medicine and feel better.
<h3>How does the placebo effect work?</h3>
Because it tricks the brain into thinking it is healing itself by releasing hormones that make you "feel good," the placebo effect is very potent. Therefore, when your doctor prescribes a placebo, they do not inform you that it has no effect; rather, they inform you that it will help you with your illness.
