The classic example is that WW1 gets a lot more attention than the Spanish flu, even though WW1 killed about 35 million people, and the flu killed between 50 and 130 million. On the other hand, the war made a huge political difference, so it might not just be a matter of intentionality.
In a history of humans (which, being a story, is mainly about choices), WW1 would stand out more prominently than the Spanish flu simply on account of the relative importance of individual prominent choices to the affair.
As everyone here knows, it would be a stupid idea to switch from airplanes to cars out of safety/terrorism concerns: Cars are a much more risky means of transportation than airplanes. But what other major risks are there that many people systematically undervalue or are not even consciously aware of?
The same can be asked for chances.
