Is an acceptable answer.
Asking people to be conclusive on the spot is a recipe for acting on bad data. There are too many biases related to stature, they interfere with accuracy.
The answer is "accepted", in the sense that it won't get you fired. But the meeting plows on, and decisions are made in absence of the answer to the question! — and never revisited once the answer is known.
And like 90% of the time it comes up, it's because the data contradicts the decision.
