Questions

Is TED worth watching?

Across the 16 videos we measured, the median Gistil Score is 68 out of 100, and 7 came out worth watching outright. The score measures how much of the runtime carries substance; it is our own measurement, not a YouTube metric.

What are the best TED videos?

The three densest ones we have measured are listed above, each with the minute its value starts — so you can open one at the second it begins to pay off.

How honest are the titles on TED?

Median title honesty across those videos is 87 out of 100 — how closely a title matches what the video actually delivers.

The Gistil Score is our own independent measurement of how much of a video's runtime carries substance. It is not a YouTube metric, not a public rating, and not the video's rating on YouTube. Gistil does not alter, download or cut any part of a video — the videos stay on YouTube and play there. Not affiliated with YouTube or Google.
