Humor can be a powerful tool in a traditional job interview, building likability and an emotional connection on both sides. The effect is compounded because humans donât have perfect recall but tend to remember the most emotionally intense experiences, as Barbara Fredrickson and Daniel Kahneman showed in a groundbreaking 1993 study. Thatâs why a well-timed joke can disproportionately impact a candidateâs evaluation. Our research (Gloor and Cooper) found that candidates who used humor during an interview increased their chances of selection by 7.9% and decreased their odds of rejection by 19.8% compared with poker-faced competitors. But the role of AI in hiring employees may be about to change this. Our review of the latest studies suggests that using humor may now be an altogether riskier strategy.Â
About a quarter of companies use AI and automation in their recruitment processes, according to a recent Society for Human Resource Management survey of 1,688 HR professionals, and about two-thirds of those use it to screen and communicate with potential candidates. A survey by ResumeBuilder.com of more than 1,000 employees involved in recruiting for their companies showed that 79% believed AI interviews would weed out suitable candidates more often than humans, while 15% of those used AI to decide on a new hire without human input.  Â
AI-assisted interviews significantly differ from their traditional counterparts. For example, a candidate may be asked to respond to automated text prompts while an AI system conducts pattern recognition tests to assess the answers against desired criteria or an ideal profile. AI may also be instructed to analyze non-verbal inputs during interviews, using still images and video to evaluate factors such as posture, voice patterns, and even the tendency to fidget. Perhaps not the best environment in which to deliver a zingy one-liner!Â
Our research shows that appropriate humor tends to be rewarded by humans, but is unlikely to win favor with AI. Why? First, does AI even get the joke? While some AI can (annoyingly) explain humor to us, it is doubtful that it can independently recognize humor without explicit cuing. Humor often involves complex linguistic patterns that require knowledge of cultural standards and norms. Take, for example, an âinsideâ joke between an interviewer and applicant, perhaps based on a shared university alma mater. This type of humor based on shared, real-world experiences would be difficult for AI to detect.Â
An AI system trained to recognize humor is also unlikely to reward it as positively as humans. Emotional connection is not part of its calculations. Even if the AI interviewer recognizes humor and has been told it is a desirable behavior, it may still penalize (or at least not reward) candidates for what it registers as a âweakâ answer. In addition, AI can struggle to learn the importance of a desirable behavior if it is uncommon. Humor falls into this category, featuring in only about 10% of professional communications, according to 2020 research by Bitterly.Â
