Randall Munroe of xkcd fashioned a scatterplot graph to compare mysteries in both their overall weirdness and their explainability. However, people will still argue over what the explanation is. Most people look at the Loch Ness Monster mystery and say “pareidolia,” while a few folks just know there’s dinosaurs in the lake. The makeup of the graph will change over time. Some day, the case of Malaysia Airlines Flight 370 will swing from the upper right to the lower middle. The tale of how the graph came to be is in the hovertext at xkcd.
