LinkedInの長文投稿の41%がAI執筆──しかも過小集計
Pangramによる100万件の投稿調査で、LinkedInは長文コンテンツの41%がAI生成と首位を独走し、X/TwitterやSubstackを大きく上回る。実際の割合はさらに高い可能性があり、ビジネスフィードの構造的汚染を示している。
a study of 1m posts from april to june 2026 revealed that 41% of long-form posts on linkedin are ai-generated, compared to 10% on substack. linkedin produced the majority of detected ai content despite making up only a third of the total dataset analyzed. the detection model, pangram 3, boasts a 0.01% false positive rate but is likely more accurate at identifying human text than ai text, suggesting the true saturation is higher. this inundation of 'slop' threatens the utility of professional networks and forces platforms to implement automated moderation against generated content.
