Part of doing research involves living with failure. (Remember, It’s not research if you don’t invite failure.) Ideally, research projects fail for the right reasons: The best reason for a project to fail is that the hypothesis is wrong and you need to think differently about your problem. Unfortunately, there are many other reasons why a project can fail. It may be that your hypothesis is correct and the failure has a different origin.

When you experience a research failure, it’s appropriate to spend some time thinking about possible reasons for the failure. Usually, it is impossible to determine why a project failed. However, in some cases the source of the failure is identifiable.

First, why do hypotheses fail?

• Because the hypothesis is wrong.
• Because the population was incorrectly identified.
• Because the sample was biased and so not representative of the population.
• Because the sample size was too small.
• Because the effect size is small.
• Because the operationalized measures are poor approximations of the theoretical terms.
• Because of a calculation or tabulation error.
• Because the control group is biased.
• Because an unidentified third variable is influencing the results.
• Because the task was too easy (i.e., ceiling effect).
• Because the task is too hard or the participants are unskilled (i.e., floor effect).
• Because the participants didn’t try (leading to a floor effect).
• Because of some demand characteristic that is causing participants to undermine the hypothesis.

Why do research projects fail?

• Because you can’t get a piece of equipment, or because of equipment failure.
• Because you have difficulty recruiting appropriate participants.
• Because you ran out of time.
• Because the cost of the project exceeded your budget.
• Because your original goal was too ambitious.
• Because a collaborator didn’t contribute as anticipated.
• Because you lost your passion or enthusiasm.
