Hindsight is always 20/20.

Had there been a vote of 20 people;  I  bet the right speaker could have swayed a plurality one direction or the other -- towards either hasty action resulting in a loss or missed opportunity, or hesitant failure to act resulting in a loss or missed opportunity.

Now it depends on the audience; if  you have 20 people who are inherently more risk-averse than ambitious or put suggestions through a highly detailed, highly technical detailed tests,   then  err in the opposite direction is likely.

The ability to persuade 20 people of something, does not necessarily align with that thing being correct, reliable, or valid.
