Yes, I am certain people are feeling the pinch, as everyone I know is.
But I am also certain that we are all sick and tired of consumer research and very concerned about what the information we provide is actually used for.
And, most of us realise that if the research is done over the computer the mere thought of being anonymous is ridiculous, as any IT man or woman can find out who we are, unless we think to defeat them, or try to, by filling in the form on the public library's computer rather than our own.
And offering to pay people for taking part in a research project does sound like a scam.
