"The average adult reads non-fiction at 238 words per minute. The average speaking pace-the speed of every podcast, every video, every audio memo-is around 150 words per minute. That's a 60 percent efficiency gap. Every time we ask someone to listen to a 30-minute podcast instead of reading a 12-minute article, we're asking for 18 minutes of their life we haven't earned."
"Research dating back to Foulke and Sticht's foundational 1969 studies shows that audible comprehension begins to break down above 275 words per minute. At that point, accelerated audio merely matches normal reading speed. You're using a workaround to achieve parity with a format that didn't need the workaround in the first place."
Companies increasingly launch podcasts as thought leadership initiatives, treating them as badges of honor in modern content strategy. However, research reveals significant inefficiencies in audio formats. Adults read non-fiction at 238 words per minute while average speaking pace is 150 words per minute, creating a 60 percent efficiency gap. Listening to a 30-minute podcast requires 18 additional minutes compared to reading a 12-minute article covering the same content. While listeners often accelerate playback to 1.5x or 2x speed, comprehension deteriorates above 275 words per minute, ultimately matching normal reading speed. The investment in podcast production lacks clear evidence of superiority over written content for message retention and audience engagement.
