That increases a user’s cognitive load, or the amount of effort and energy that it takes to complete a task.

The WCAG is adding cognitive metrics as part of Web accessibility. It is more important that we start focusing on how to reduce load. One thing that bothers me so much about having ADHD is modal pop-ups, especially when I don't do anything to activate them. I was using an app that kept having modals open as part of the tutorial all the time. All I wanted to do was use the damn app, and If I needed help, I could click on the help button. If I visit a site that has a modal pop-up at any point asking me to subscribe, I will boycott and never return.
