Whenever he travels to Denver for business meetings, Calvin notices that he gets bad headaches that don't go away until he returns home to Toronto. He assumes that it is just the travel that causes his migraines, but he does not consider that the elevation change and atmospheric pressure might be at fault. Calvin is making incorrect conclusions about his headaches.

Medical

Explanation:

Calvin experiences headaches whenever he is away from Toronto to Denver for business meetings which stops whenever he comes back to Toronto.

He assumes it's the travel related stress but doesn't take other factors into consideration such as change in atmospheric pressure and elevation change.

His medical conclusion about the headaches is incorrect because it was not caused by travel related stress but by other factors like major differences in the geography of the two states.
