The campus safety committee has asked professor ibrahim to study bicycling on his campus. he trains two observers and has them observe the number of cyclists and their safety at various points around campus. both observers are very interested in the topic because they have been struck by bicycles. which threat to construct validity should concern professor ibrahim even if the interrater reliability is high?

Socially desirable responding.

Explanation:

In social science research, social desirability bias is a type of response bias that is the tendency of survey respondents to answer questions in a manner that will be viewed favorably by others. It can take the form of over-reporting "good behavior" or under-reporting "bad," or undesirable behavior. The tendency poses a serious problem with conducting research with self-reports. This bias interferes with the interpretation of average tendencies as well as individual differences.

As both observers have been struck by bicycles, their response might be biased.
