In an emergent situation, you'll never understand all the data in time. Imagine a loved one that's hurt who calls you for help after a crash. You could spend time trying to figure out their symptoms and their feelings, probing them for more information to make an accurate decision so that you don't have to actually waste the time to go over to them physically. Or you could just go over immediately and potentially waste time when it turns out your loved one would have been just fine without you. Most people choose the latter.

There's a reason emergency services dispatchers have such a stressful job, they're making these decisions all the time based on very limited amounts of data. Unfortunately we're all living in a situation right now where we're making emergency decisions as new information emerges.
