Is The Irrational New Tonight? (February 11, 2025)

Mercer and his team always love a puzzle on NBC's The Irrational.

By Jessica White

Season 2 of The Irrational has been delivering some mind-boggling action, and fans never tire of watching Alec Mercer (Jesse L. Martin) and his crew of behavioral experts crack the next case.

How to Watch

Watch The Irrational Tuesdays at 10/9c on NBC and next day on Peacock

Mercer's expertise surrounding the human mind has made him a valuable asset for authorities; whether it's a mystifying murder scene or a befuddling social phenomenon, you can rely on Mercer and his team to get to the bottom of it. The human brain can be puzzling, but Mercer never fails to solve the mystery.

"There are so many possibilities when it comes to just concentrating on how we think and how we behave," Martin told Collider. "Mental health is a big topic on everybody's platforms these days, and our show explores it, certainly in a scripted context, but in so many different ways with so many different people. The more interesting actors we get in, the more that behavior surfaces... There are so many places to get creative. There are so many stories that can get told when you're just talking about behavior, in general."

"We are so lucky and privileged to have Jesse Martin playing the role of Alec," showrunner Arika Lisanne Mittman told NBC Insider. "When I first wrote this character, there was a character I wrote on paper, and there's what Jesse brought to it, and those two things put together have just created magic, and I'm so grateful to have him.
