In research and psychology, the placebo effect refers to the phenomenon that occurs when people experience a benefit in their health after the administration of a substance with no real medical effects (an inactive substance).

In this example, in a study to determine the effect of caffeine on memory, participants receive either a caffeine pill or a sugar pill. Sugar is a substance that has no real medical effects when it comes to memory and that has no caffeine, in other words, it's an inactive substance. However, the participants that received this treatment had a small increase in memory. Therefore, they are experiencing a benefit after taking an inactive substance (the sugar pill) and this would likely be due to the placebo effect.

answer; i believe that the correct answer is (scientific approach)

it is a part of john locke's natural rights popular during the age of enlightenment that people had inalienable rights to life, liberty and property. this was reflected by thomas jefferson in his declaration of independence as rights to life,liberty and the pursuit of happiness.

another line in the declaration of independence is that people have certain rights just because they are human. humans are capable of obeying the three natural rights john locke mentioned making them governable by these laws and therefore entitled to these rights as well.
