The attention span of a goldfish is 11 seconds according to The Coffee News. Other sources say 9. Far older sources suggest 3. I’m neither sure how the attention span of a goldfish is measured nor how the measurement ranges from 3-11, but clearly the goldfish is getting smarter. The attention span of humans has recently been compared to that of a goldfish. This research must be very complicated; though, to be honest, my news feed provides time-to-read information at the end of every article, e.g.., 3 min, suggesting a short attention span indeed, though much larger than that of a goldfish. I doubt the average goldfish could read even the shortest of these articles.
