Reasoning detection in CoT

METR's grouped bar chart drew 64.8K views on X: 0.4x its typical post and #24 of 26 METR charts we track by views. Read Oct 10, 2026.

Prior work has found that Chain of Thought (CoT) can be unfaithful. Should we then ignore what it says?

Why it spread

This chart post spread because it paired a sharp question about whether to ignore Chain of Thought with a grouped-bar chart showing that complex reasoning is easier to detect than faithful reasoning, and it drew 302 likes, 34 reposts, 14 quotes, 145 saves, and 64,827 views from an independent author whose quote rate sits in the top quarter.

What worked

  • The post opens with a direct tension: prior work found Chain of Thought can be unfaithful, then asks whether we should ignore what it says, which makes the chart feel like an answer to a live debate.
  • The chart type is a grouped-bar comparison and the stated takeaway is simple and memorable, that complex reasoning is easier to detect than faithful reasoning in CoT.
  • The account is an independent author with a top-quarter quote rate, and the post is branded with a source line, so the chart reads as a citable research artifact rather than a loose opinion.

What to borrow

We could reuse the same framing by starting with a common assumption in our own area, asking whether it should be discarded, and then showing a grouped-bar chart where the key contrast is easy to state in one line.

Careful

Do not copy the specific claim that CoT is informative about LLM cognition, and do not over-read the engagement as proof that the finding is settled, since the numbers show attention and debate rather than consensus.
