I enjoy your travel articles, but here are some reasons people might click on the negative more often:

1. When you read a novel, you like conflict, drama, resolution. All those things stir your emotions, and it's the same with articles.

2. We read about negative things hoping to fathom why, so we can avoid them or make sense of them.

3. We read these things hoping there is some redemption, some hope or something positive to come out of the situation that can soften the sheer senselessness of it all.
