This is important. With group thinking and peer pressure, many of us forget that if we have concerns we should voice them.
Is the data questionable?
Is it the level of risk?
Is it because you are not used to navigating the unfamiliar?
Is it the tension?
Am I hesitant to speak up because of how much we have invested?
Am I afraid to admit I was wrong?
Is it because it might fail?
Maybe you don’t have permission?
Is it the fear that is getting in the way?
If you are not comfortable, you should make it known. And make it clear why it is you are not comfortable.
The sooner you make your objections known, the better we can work through the process to get to the point of decision. Even if that means turning around.
