Focus Insite prefer to design ‘blind’ studies so as not to bias the study outcomes, but this isn’t always possible for medical or healthcare studies. You’ll have more success recruiting medical professionals when you can share more details and particulars of the study you’re trying to fill. This doesn’t mean you have to ‘spill the beans’, it just means that you might need to divulge more information about the study in order for participants to feel comfortable and confident that their time will be well spent by participating.
