If an object isn't to scale with its surroundings, it's easier to overlook, according to a study published last week in the journal Current Biology. Participants were asked to search an image for a particular object. Sometimes the object was missing, sometimes it was normal-sized, and sometimes it was four times larger than normal. Participants were 13% more likely to miss the object when it was larger than expected.

Why it matters: It's part of a larger body of work showing expectations can influence how we perceive the world around us. Similar phenomena explain why sometimes objects we were looking for were in front of us the whole time, just out-of-context.

Driving the news: As political arguments on Facebook’s employee discussion boards have grown more heated and divisive, the company ordered new restrictions on the forums earlier this month, which run on Facebook’s Workplace platform.

Amy Coney Barrett's likely ascension to the Supreme Court would affect climate policy beyond shoving the court rightward in the abstract.

Why it matters: If Joe Biden wins the presidential election, his regulations and potential new climate laws would face litigation that could reach the high court.
