Professor Mercer’s work won’t continue into the 2025-26 TV season. NBC has cancelled The Irrational so that we won’t see a third season. The show’s second season of 18 episodes finished airing in March.
A police procedural drama series, The Irrational TV show stars Jesse L. Martin, Maahra Hill, Arash DeMaxi, Travina Springer, Molly Kunz, and Arash DeMaxi. Professor Alec Mercer (Martin) is a professor and world-renowned expert in behavioral science, so he has unique insight into human nature. He lends his unique expertise to various high-stakes cases involving governments, law enforcement, and corporations. In addition to his fierce curiosity about human decision-making, Alec also has support from grad student assistant Phoebe (Kunz), grad student Rizwan (DeMaxi), his tech-savvy younger sister Kylie (Springer), and his estranged wife, FBI Agent Marisa Clark (Hill). Years ago, Alec was the victim of a church bombing, and his early research was motivated by this trauma. His missing memories start to resurface when he meets a convicted bomber who comes up for parole.
Airing on Tuesday nights, the second season of The Irrational averaged a 0.17 rating in the 18-49 demographic and 2.09 million viewers (includes DVR playback through 3:00 AM). Compared to season one, that’s down by 37% in the demo and down by 39% in viewership.
The show had a decent run last season, but the ratings fell off in season two. NBC will also be airing many NBA games next season, leaving fewer slots available on the schedule.
Today, NBC also cancelled Found, Lopez Vs Lopez, Night Court, and Suits LA.
What do you think? Have you kept up with The Irrational TV series? Are you disappointed this NBC drama wasn’t renewed for a third season?


If NBC really wanted to get viewer loyalty they’d implement “every show deserves an ending” and do like they did with Timeless a two-episode/movie to wrap up as much as they can, so the previous seasons have some re-watch value and not a path to an unfinished story. That is how you protect what you already invested in producing having rewatch value, earn favor with the fans, and making it a Peacock exclusive can drive those viewers to the streaming service, and will give audiences the wiliness to try out new NBC scripted shows.
I don’t understand NBC, they are cancelling 2 really good shows, The Irrational and Found. It seems like all they want on is so called “reality” shows, which are FAR FROM REAL! Dateline is now the only show on NBC worth watching. So sad to see those good shows cancelled.
THE IRRATIONAL was a great show and you decided to cancel it!!!! I am definitely disappointed. I looked forward to watching it.
I think this show and Found were the only ones I watch from NBC. From what I saw of what they plan to do next fall, I don’t think I have anything to watch from them. Oh well.
I am gobsmacked, at the cancelling of the great shows!!!!!!!!!
I absolutely love this show and am gutted that it’s being cancelled! It was so well written and acted and I’m going to miss seeing Jesse L. Martin on a regular basis. He is such a wonderful actor!
I’m SO tired of great shows being. Canceled!
Me too!
Once again these networks continue to cancel shows that don’t follow reality show platform. This actually a good show with good character development,
Taking all the black shows off tv
Not going to miss this show. It was a bit boring and I didn’t care for the storylines.
