The IDRLabs Big Bang Theory Test is inspired by psychometric methodology and based on research into the characters in the Big Bang Theory.

The test provides feedback such as the following:

Sheldon Cooper: Sheldon Cooper, a world-leading theoretical physicist with no clue how to navigate the subtle art of normal conversation, is an eccentric genius with an ego to match his talents. His brilliance in the field of physics is unparalleled — a fact he frequently lords over his friends. Despite his talents, Sheldon's obsessive-compulsive tendencies and rigid adherence to routines make navigating the social world a constant challenge. His literal interpretation of language, coupled with a lack of empathy, often means he misunderstands how to act in social situations. Because of this, he doesn’t get along with most people. Luckily, he doesn’t mind this, as he is content to spend time on his own and have his head buried in his passions, such as comics and video games. Sheldon is endearing due to his naivety, particularly in the realm of romance. But he is also frustrating due to his inability to see beyond his own perspective. Despite his difficult personality, his highly unusual way of seeing the world makes him one of the show’s most beloved characters.

Leonard Hofstadter: Leonard Hofstadter, kind, romantic, and nerdy by nature, is an experimental physicist who is desperate to help his insular, quirky social group branch out and become more social. Unlike his roommate, Sheldon Cooper, Leonard is more socially adept, providing a bridge between the highly intellectual world of the main characters and the rest of the world. He provides a relatable entry point into the scientific subculture depicted in the show, maintaining a love for traditionally nerdy things like Dungeons and Dragons, he is ready to move on from the phase in his life that those pursuits were synonymous with. Leonard's intelligence is notable, though it is overshadowed by Sheldon's brilliance — which makes him insecure even though, by any normal standard, his brilliance would stand out. Despite being somewhat more socially competent than his friends, Leonard still faces challenges in relationships and often finds himself entangled in humorous and awkward situations. Despite this, his endearing, down-to-earth nature eventually leads to an unlikely relationship with his beautiful neighbor, Penny, which forms the romantic heart of the show. Leonard becomes the unlikely hero of a nerdy teenage dream – to ‘get the girl’ and still be able to play video games with his friends.

Penny Hofstadter: Penny Hofstadter, a beautiful aspiring actress with a sarcastic wit, brings a refreshing contrast to the highly intellectual and socially awkward world of her friends, particularly her neighbors Leonard and Sheldon. Penny works as a waitress at The Cheesecake Factory, a job that she dislikes but allows her to be independent and live out her dream. Her down-to-earth personality, street smarts, and social skills often clash with the esoteric, unconventional way her less socialized friends view the world. Penny's character is defined by a blend of warmth, humor, and resilience — she is very caring towards the group and understands the need for her to initiate them into some of the practical realities of the world that they find hard to see. Her surprising romantic relationship with Leonard proves that she is not shallow in love, as she clearly values Leonard’s kind, endearing nature over the looks of some of her previous boyfriends. Penny’s sarcastic dynamic with the other main characters forms the basis of the show’s comedy and makes her a much-loved part of the world of the Big Bang Theory.

Howard Wolowitz: Howard Wolowitz, a wannabe Lothario with a talent for invention, is the charismatic aerospace engineer whose doomed schemes to seduce women ultimately make him a loveable, sympathetic figure. Despite his scientific background, Howard stands out among his friends for his flamboyant personality and eccentric fashion sense. Howard's constant, often unsuccessful, attempts at flirting and exaggerated tales of romantic conquests are his way of covering up his embarrassment of still living at home despite being an adult. His tumultuous relationship with his mother, who never appears on screen, is an endless screaming match full of comically misheard sentences. However, it is his relationship with his mother that helps him bond with his future wife, Bernadette, whose mother is also incredibly overbearing. Howard eventually transforms into a more mature husband figure, showing that once he feels loved, he is able to be a far more caring, and sensitive person. His zany personality, incredible repertoire of impressions, and charming relationship with best friend Raj, make him an important part of the tapestry of the show.

Rajesh "Raj" Koothrappali: Rajesh "Raj" Koothrappali is a loveable astrophysicist who initially struggles with selective mutism, rendering him unable to speak to women unless under the influence of alcohol. Raj is best friends with Howard, and despite their near-constant bickering — which leads other characters to compare them to a married couple — their friendship is a winning aspect of the show. Despite his anxiety around women, his drunk persona is completely different and is actually quite successful with women. Raj eventually overcomes his selective mutism, becoming more socially confident as his bonds with his friends grow. Raj’s Indian heritage is a source of comedy in the show, and whilst at times he is the butt of jokes because of it, he is also often able to use it to his advantage. Raj also originally claims to have had humble beginnings, but it later becomes apparent that he was using this sympathetic image to hide his family’s wealth. By eventually becoming financially independent from his parents, Raj demonstrates his considerable personal growth and cements his character as a firm fan favorite.

Bernadette Rostenkowski: Bernadette Rostenkowski is proof that good things come in small packages. As a microbiologist with a small stature and a high-pitched voice, you might think she’d be sweet and cuddly. You’d be wrong. In fact, she demonstrates an ability to wield power with a sternness and natural authority that belies her unassuming appearance. She is able to use these techniques to manipulate and distract people in order to get what she wants, but she is not at all selfish and is often amenable and caring toward the rest of the group. Initially introduced as a waitress at The Cheesecake Factory, Bernadette pursues her career in microbiology with fierce determination, showing that she is a strong, independent woman. Her unlikely relationship with Howard allows both characters to put aside their negative family pasts and forge a new, more positive vision of what a family should be like. Bernadette brings a mix of humor, warmth, and a strong sense of self to "The Big Bang Theory," making her a beloved and integral part of the series.

Amy Farrah Fowler: Amy Farrah Fowler, initially introduced as a female version of Sheldon, is a neurobiologist with a Ph.D. who becomes a unique and interesting character over the course of the show. Initially introduced as socially awkward and reserved, she becomes more expressive and relatable as the show goes on – perhaps most obviously in contrast with Sheldon’s refusal to change his strange, quirky ways. She evolves from a character with limited social skills and a narrow focus on her career to a more confident and well-rounded individual who forms close friendships with the other characters, particularly Penny and Bernadette. Her romantic relationship with Sheldon is atypical and far from any traditional vision of love, but their quirky characters mesh well together and allow them both to grow to understand the world beyond their admittedly rather similar perspectives. Providing a romantic match for the seemingly undateable Sheldon makes Amy a hilarious and vital part of this much-loved show.
