CH’s are simply using the ratings which SH provides.
Does everyone remember those tests way back when where you had 4 selections and you had to decide which one wasn’t like the others? Well, look at the rating choices that CH’s have, then pick the one that doesn’t quite fit.
Right, the ‘no, thank you’ option doesn’t fit with the others. ‘No, thank you’ should just be removed from the rating selection. It only has a negative purpose, that same purpose can be transferred to the ‘on the right track’ rating but in a more positive way.
What is happening is that CH’s get in the habit of being negative over and over again and they come away from this whole experience with negative feelings. When you are selling anything, the last thing you want to hear is the word no and here we are encouraging the client to say no hundreds of times. The ‘No, Thank You’ option should just be removed.
SH could also add a new rating mechanism after the names have been submitted, something like a star to highlight the top contenders. SH could then freeze the prior ratings and only allow them to rate top contenders with a star or some other icon.
