World-renowned behavioral science professor Alec Mercer uses his unique expertise in psychology, body language, emotion and more to help solve difficult, high-stakes cases. With the support of his research assistants, his tech-savvy sister and his ex-wife -- who also happens to be an FBI agent -- and guided by his fierce curiosity about human decision-making, Mercer truly has solving crime down to a science. By asking the right questions, making observations no one else can and studying every scene in new ways, there's no case too tough for his brilliant mind to crack -- except maybe his own mysterious past.

What to Know

Critics Consensus

The Irrational could've used a lot more originality to live up to its promise, although Jesse L. Martin's shrewd presence makes even the utterly conventional pretty watchable.

While the true culprits of the crimes are usually glaringly obvious, a few stunners here and there make “The Irrational” enjoyable primetime viewing. It’s a classic drama that viewers can dive in and out of without missing a beat. Go to Full Review Verne Gay Newsday 10/03/2023
2.5/4
Overall, "The Irrational" is decently acted, competently written, and adequately directed. You will learn fun things, and presumably true ones, about behavioral science, as well as its forensic applications in police work. Go to Full Review Brian Tallerico RogerEbert.com 09/26/2023
“The Irrational” works because it has a likable cast and reasonably tight plotting, even if every episode so far seems to rush to its conclusion. Go to Full Review Jen Maravegias Pajiba 10/04/2023
Irrational is a “just fine” show that hits above its weight because of its lead. Come for Martin showing off his strong leading-man vibe. Stay for the middling mysteries and sharp outfits. Go to Full Review Matt Roush TV Insider 09/30/2023
3/5
Thankfully, Martin rarely sheds his cool-cat persona, even when, to the dismay of his FBI agent ex-wife (Maahra Hill), he risks his neck to crack a case. Sounds irrational, but that’s how Mercer rolls. Go to Full Review Monique Jones Common Sense Media 09/29/2023

See more Sydney L @RT23836370 12/14/2024 Great show with a really good cast; enjoy all the characters and the glimpses at the interesting science/profiling. See more Suresha H @RT76303478 11/27/2024 This is such a unique way to look at why things happen the way they do and how often subconscious factors drive decisions. See more AM J @AMJORDAN 10/28/2024 A solidly good, very enjoyable watch. Jesse L. Martin has fantastic presence and he's surrounded by an interesting cast of characters. Each episode is a completely different scenario & there's a nicely woven thread of continuous stories about the main cast through it all. I found the science fascinating & really enjoyed watching it applied to real life situations. I binge watched the first season & was disappointed there were only a few episodes of S2 out. I'll wait eagerly for the next one & hope they get renewed for S3! See more Irina B @RT34155209 10/15/2024 Caught The Irrational: Season 1 on Peacock recently and thoroughly enjoyed it. Can't wait for each new episode of Season 2. See more Read all reviews
