The Great LinkedIn Rewrite: Workers Are Retroactively Adding AI Skills

Stanford economist Nicholas Bloom and researchers from Revelio Labs analyzed 29.4 million LinkedIn profiles, identifying a phenomenon they term "time travel." Since the release of ChatGPT, the retroactive addition of terms like "AI," "GPT," and "LLM" to concluded roles has surged sixfold. While these professionals scramble to appear tech-forward, they are simultaneously scrubbing their profiles of remote-work terminology and diversity-focused language. Mentions of "remote" and "WFH" have plateaued, while references to "DEI" saw a sharp decline following executive orders in early 2025.

This behavior is most pronounced in the technology sector, where 31.6% of users have edited past roles—far exceeding the 19.7% average across all industries. Researchers note that the median edit occurs more than four years after a job has ended, signaling a strategic attempt to mirror perceived employer priorities. Rather than indicating widespread fabrication, these updates reflect a "re-branding" of legacy experience to fit the current market. Consequently, the study warns that modern LinkedIn data serves as a moving target, with 2026 snapshots likely overstating the prevalence of AI skills in 2022 by roughly 30%.
