BETHESDA, MD.—Researchers at the National Institute of Behavioral Sciences (NIBS) announced Wednesday that they have successfully decoded the phrase "we should get coffee sometime," classifying the common utterance as a specialized social signal designed to terminate an interaction forever.
The three-year, $3.4 million study, which relied on extensive focus groups and behavioral tracking of 4,200 adult subjects, concluded that the phrase carries no logistical intent. Instead, researchers discovered that "we should get coffee sometime" serves as a non-binding linguistic placebo, allowing both parties to mutually agree to end an encounter without the discomfort of explaining why they do not wish to see each other again.
"For decades, sociologists treated this phrase as a literal, albeit vague, invitation to consume caffeinated beverages," said Dr. Aris Thorne, director of the NIBS Cognitive Linguistics Lab and lead author of the study. "However, our focus group data revealed a stark reality: when a subject utters the phrase, the probability of them actually scheduling, purchasing, or drinking coffee with the recipient is statistically indistinguishable from zero."
According to the study's findings, published this week in the Journal of Applied Human Dynamics, the phrase operates through a mechanism researchers call "non-binding temporal projection." By invoking a hypothetical future event—"sometime"—without specifying a day, week, or decade, speakers can simulate warmth while initiating a physical retreat.
Focus group participants placed in simulated awkward encounters, such as running into a former college classmate in a grocery store aisle, exhibited elevated heart rates and micro-expressions of panic until the phrase was deployed. Upon uttering the phrase, cortisol levels in both parties dropped by an average of 42 percent, prompting an immediate physical separation.
"It is a highly efficient social emergency exit," said Sarah Vance, a behavioral analyst who assisted with the focus groups. "When a participant says, 'Yeah, let's do it, I'll text you,' they are not opening a dialogue. They are signaling that the transaction is closed, the ledger is balanced, and both parties are now free to walk toward the exit."
The study also tracked the digital aftermath of these encounters. Out of 12,800 documented instances of "we should get coffee sometime" observed during the research period, only five resulted in actual meetings. In all five cases, researchers noted, at least one participant was suffering from a cognitive misunderstanding of local social norms, resulting in "extreme mutual discomfort" during the actual coffee consumption.
With the baseline mechanics of the phrase now scientifically established, the NIBS team plans to secure funding for a five-year follow-up study investigating the phrase "I'll let you know," which preliminary data suggests is a declaration of total social bankruptcy.
