When recruiting for usability testing, is the person’s job/profession important? If they are a UX professional, will their test still be valid? This question came up when one of my staff members told me they had been recruited to participte in a test by a local company (who probably reads this blog occasionally, btw) who did not ask what she did for a living. I had to think that as someone who prepares for an observes a fair number of usability tests, this person might not make the best test subject. Is my instinct correct, or is profession irrelevant when it comes to testing?
