In an Online Survey, People Were Asked If They Would

Multiple Choice

In an online survey, people were asked if they would cheat on their partner if there was no chance of getting caught. Approximately 23,000 Internet users responded to the survey. Almost half of those responding said they would not, while the other half said they probably would. What is a significant limitation with surveys like this one?

A) Not enough people responded to the survey, which means the results are not valid.
B) The survey involved respondents who volunteered to participate, so the sample was not representative of the population.
C) There was no experimental control group.
D) The survey did not follow a double-blind procedure, which means that expectancy effects probably slanted the results.
