When I do software testing, I need a variety of test cases, and sufficient quantity of test runs. Then I come to a conclusion that there is an X% chance that the experience in production will be consistent with the requirements.
Considering the amount of test data, test cases and test runs (or their equivalent) there is way to make a prediction above 50%, the flip of a coin, on the origin of man, or on climate change, or on a myriad of topics.
Did humans originate in Africa or Turkey? Flip a coin.
Will there be a global warming trend? Flip a coin.
Which coins, in that case? Seems like the answers to those questions are on neither side.
