"Do you know what Blu-Ray is?" if they answer yes how do you know they know what Blu-Ray is?
By following with an open question. "Great. Can you please explain the benefits?"
When 80% of people hang up because they don't want to deal with another telemarketer, and a disproportionately large portion of the remaining people are vdeophiles (who are happy someone is finally asking them about something important to them) how do you get a random sample?
Could also be the other way around you know? But there are ways to entice people into participating, for example there's a small survey firm nearby where I live. For example if they do a cigarette survey, they hand out money or free cigarettes (all kinds of stuff actually), some people stand in front of the supermarket to invite people into the next door building if they smoke, takes only 5 minutes of their time and the bulk of people do participate.
