If Google intentionally slowed its search results by 10%, would people not spend more time on the site? Perhaps even to the tune of 10%? But would people suddenly love Google 10% more?

As a more explicit example, Facebook used to allow you to type a friend's name into the search bar on desktop, and a card would come down (with other possible people too you could select/down-arrow to) so when you hit enter you would go straight to that friend's page. Now, all search queries take you to a search page, where you can then click on your friend's name. That extra page load and click multiplied a few times a day probably keeps me on Facebook an extra minute or so every day, which I'm sure was used during the feature testing to justify its greatness. Instead, it noticeably and nearly daily negatively impacts my life.
