Google Testing “Simple Search” Refinement Choice

Google may be testing a new “Simple Search” feature that may dumb-down the search results when you want something more simple. Google shows the “Simple Search” +Topics refinement button at the top of the mobile and desktop results, when tapped on, it readjusts the results to give you a different set of results.

Here is a screenshot from @dansully, he sent me more photos similar to what he posted on X:

Plus, I cannot replicate this at all, either on desktop or mobile but Dan can.

Can you replicate this?

What do you think “Simple Search” is and does?
