A famous example of the difficulty in experimental design is the Hawthorne Effect. Studies were done in the Hawthorne Plant of Western Electric in Illinois between 1927 and 1932 to determine if the effect of lighting, humidity and other factors affected employee productivity. It was discovered that the mere fact of doing the experiments, independent of which factor was changed, had a significant, positive effect on employee productivity. It is thought that the extra attention employees received during the experiments was the most important factor driving productivity.Think of a situation in where you work. What are some of the reasons that experiments in the workplace may be difficult to conduct?2) Lurking variables are a challenge to good experimental designs. Lurking variables are variables that aren't being studied or controlled for but that have an effect on experimental results. In medical experiments, real effects often come from no physical cause, and those effects must be taken into account when testing new medications (thus we need to consider the placebo effect). For example, if we give some people a new drug for curing the common cold, and they get over their colds more quickly than people who did not take the drug, was it the drug or the placebo effect that shortened the cold?To help identify these lurking variables, let's discuss the following about experiments related to child-rearing techniques and the nature vs. nuture debate. Why are behavioral studies like this so difficult to conduct?
