And the poor shlubs like me working the phones are pressured to sign up as many people as we can in as short a time as possible. Telemarketers who don't meet production quotas suffer the consequences. And this is true, up to a point. But where I worked it was easy to outsmart the monitors by sitting near the monitoring station. A quick glance would reveal whether I was being monitored or not.
Research is only as strong as the weakest link in the process.
With so many people with so many reasons to fudge the truth, it is surprising any valuable information comes out of this kind of research. From Flaubert and Thomas Hardy to Theodore Dreiser and Reynolds Price, men have created complex, three-dimensional female characters and made them the protagonists of some of their greatest works. Women have generally been unable to develop similarly sophisticated and nuanced male characters. Price himself once asked his professor at Oxford why this was the case. I still often smile at strangers, make small talk in the grocery line and greet neighbors I don't know.
