A new-to-me feature in Google is a link which appears when one searches for a local entity (e.g. a business) and asks the searcher to confirm or correct the entity data.
A search for Elliott Bay Books produces this:
Clicking on the ‘Is this accurate?’ link brings up the ability to confirm or ‘cancel’. Cancel here means to drop out of the interaction, so essentially all you can do is confirm the data.
This only appears to happen when the result is in the top of the SERP (i.e. not when the Local business results appear interleaved with the organic blue link results. This interaction appears to surface when the business information is presented in isolation with a map (i.e. not when there are multiple locations positioned on the map.
This post on Search Engine Roundtable suggests that this feature surfaced late October.
Reading the SER post forced be to go back and re-read the interaction which I now see asks you to confirm ‘This address, phone number, map or business info is not accurate.’ Confusing. You are asked to confirm that the data is incorrect.
