Which bias best describes a scenario where a developer creates an algorithm for a social media platform, which sends the user post ads and articles that causes more unsettling feelings, anger, and upsets the user so the user tends to click on them, or creating more revenue

The bias that best describes this scenario is confirmation bias. The developer is selecting and promoting content that elicits negative emotions in the user because it is more likely to lead to clicks and generate revenue. This bias is leading the developer to seek out information that confirms their pre-existing belief that negative content will be more profitable, while ignoring potentially more positive or neutral content that could also be of interest to users.
