One of the disadvantages of experimental research is that
a. it isn’t easily replicated
b. it doesn’t often reflect reality
c. the results aren’t generalizable
d. conditions are not controllable

The correct answer is: b. it doesn’t often reflect reality.

While experimental research has several advantages, including: investigating the effect of one variable on another, and the ability to control and eliminate confounding variables, it also has one major disadvantage. This disadvantage is known as: lack of ecological validity.

Lack of ecological validity means that the findings of research study might not be generalizable to real-life settings, and might only apply to laboratory settings. To avoid the problem of ecological validity, and to increase the validity of an experimental research study, a study should be conducted in natural settings when possible.
