The is also numerical difference. If 1 million people see the earth as round and 1 see the earth is flat, chance is high (but not absolute) that the 1 person is in error. The reverse is also true, if 1 million people see the earth as round and 1 see the earth as round, chance is high (but not absolute) that the 1 person is in error.
There is degree of experience. If a 10-year experience doctor judges the patient to have cancer and a 0-year experience doctor judges as have-not. Chance is high (but not absolute) that the 0-year experience doctor is in error.
Not to mention there are talented individual who is naturally better at evaluating certain decision.
------------------------
Because of the nature of .. nature, we can never obtain anything in great certainty. Instead, we are always forced to make choices base on "educated guess".
When in doubt, attempt a small scale experiement? Move in little step?
If there is a debate going on, perhaps we can wait a bit for the big decision. If we have a situation where everything being equally reasonable, let the error be on the "living" side because "death" is irreversible. (We can always regret and put someone to death. We can't regret and resurrect a dead body.)
