In response to my recent email, one researcher wrote to me and said:

“What you say about 'torture to give up her secrets' reminds me very strongly of my days of doing market research, when you were desperate for the participants to say something in a way which you could incorporate as a quotation in your report - and which clients would appreciate!  This led to some pretty desperate forms of interviewing at times, too.”

This may (w)ring a bell with other researchers, too!

Best wishes
