The time is takes to make a decisions increases with the number of choices available t the user.
Google Homepage keeps decisions requited to enter a keyword tp a minimum by eliminating any additional content that could distract the user from the act of typing a keyword in.
Apple TV Remotes also don't require a substantial amount of working memory, therefore incurs less cognitive load, only a few buttons can allow users to not be overwhelmed, by transferring the complex information to the TV interface, information can be organised within menus.
As designers we need to ensure that we are not overwhelming the user by giving them multiple choices when response times are critical to decrease decision time, to avoid this we can highlight recommended options. Breaking tasks into smaller steps in order to decrease cognitive load, and using progressive onboarding to minimise cognitive load for new users. Although we also need to be careful not to simplify to the point of abstraction.
