Why don't psychologists use random samples often?

Answer 1

It is impossible to obtain a truly random sample. Psychologists will endeavour however to have a sample as random as is possible given the constraints of the study. Indeed there are often factors that make it difficult to obtain randomness, for example geographic location. So to answer your question, it is not that psychologists avoid the random sample, in fact, they prefer it when it is obtainable however this is often not the case.

Answer 2

Psychologists may not always use random samples due to practical constraints such as time, resources, and accessibility to diverse populations. They may also prioritize other sampling methods like convenience or snowball sampling based on their specific research questions and goals. Additionally, some research designs may not require random samples as long as they adequately represent the population of interest.
