Engagement
A typical post picks up 68 interactions against 455K followers, an engagement rate of 0.015%. Measured over 18 original posts, its engagement rate beats 40% of 20,444 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 10K times each, and 0.66% of those impressions turn into an interaction. That is about 2.28% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 0.9 post a day over the last 30 days, with activity on roughly 53% of days. Most posts go out around 20:00 UTC, and Monday is the busiest day of the week. Of the 18 posts sampled, 56% carry an image or video and 61% link out. The account's strongest tracked post pulled 1.1K interactions, about 16x its own typical post. Recurring topics include #aliens, #seti, #lawrencekrauss.

Compared with accounts its own size
Lawrence M. Krauss's engagement rate beats 40% of the tracked X accounts closest to it in follower count (20,444 accounts, accounts of similar size (decile 10 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.
On engagement per impression rather than per follower it beats 37% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.

Posting timing
This account posts most often around 20:00 UTC, and Monday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

Formats this account uses
Its own posting mix on the left, and what each of those formats does across every account we track on the right. Only formats where the effect clears our publish test appear here, so an empty row is a format we could not measure rather than one that does nothing.
| Format | This account | Catalog effect | 95% interval | Accounts behind it |
|---|---|---|---|---|
| Image or video | 56% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 61% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | no effect | -2% to -1% | 42K |
- 56% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 111% above the same accounts' other posts.
- 61% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts, so a large share of this account's output sits in the weakest bucket we measure.
- Its average post runs 254 characters, which falls in the 180 - 280 characters band. Across the catalog, posts of 180 to 280 characters match the same accounts' other posts almost exactly.
These are catalog-wide differences applied to this account's own posting mix, not a measurement of how each format performs for this account specifically. We keep one median per account, not one per format per account, so the second thing is not something this data can tell you.

Richard Feynman was amazing in so many ways. Was such an honor to both know him and write his scientific biography. https://t.co/weckZLcQNJ

The Jason Arday debacle reflects problems with schools of education as much as it is an indictment of Cambridge. In my experience the scholarly standards at education schools can be second rate and what passes for research can be laughable. Not sure what purpose they serve at universities. Perhaps it is better to educate students in real fields at universities and then have separate one year vocational teacher training institutes that don’t have the pretense of being research institutes.

Starting a podcast soon with @LKrauss1 where we investigate and talk about phenomenal claims. Much of it will be in the spirit of James Randi, but with our own twist. We will delve into everything from telepathy to frontier science. Hint: He's Scully and I'm Mulder.

Bernie Sanders may be the worst thing that has happened to the Democrats. He helped get Donald Trump elected in 2016 & his support of leftist populists could blow what should (given a bumbling unpopular president & a do nothing congress) be a good chance of regaining power

Ok. I am going to wade in. I saw The Odyssey in Cyprus on the say it opened. It was ok. My issue was the casting. Nothing to do with gender or race. I just found every character, with the exception of Charlize Theron, to be horrifically mis-cast. Unknowns would have been better.

Using quotas based on identity politics for Canada Research Chairs. rather than hiring based on excellence is hurting Canadian science, as this study demonstrates. Shameful. https://t.co/6ChmN2NVMy

Second trip up the west coast 1k miles without touching steering wheel. @elonmusk the only thing that would improve things is if I could say “engage!” and self driving would take over! Am I missing something?

Ranked by total interactions across everything we have tracked for this account, which is a longer history than the 30-day window the rates above use. The multiple compares each post to this account's own median.
Recurring topics
The most frequent hashtags in the sampled posts. They describe what this account writes about; they are not a performance signal, and the catalog-wide breakdown on the hub shows how little hashtag count moves.

- What is Lawrence M. Krauss's engagement rate on X?
- Lawrence M. Krauss (@LKrauss1) has an engagement rate of 0.015%, based on the median interactions across 18 original posts from the last 30 days against 454,753 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.015%, Lawrence M. Krauss sits above the 10th percentile of the 204,798 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
- Does @LKrauss1 have real engagement?
- Its engagement rate beats 40% of the tracked X accounts closest to it in follower count (20,444 accounts), which puts it in the middle of its size range group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
- When does @LKrauss1 post?
- Most posts go out around 20:00 UTC, and Monday is its busiest day, at roughly 0.9 posts per day across the measured window.
