HSRP-499

Echo chambers are real but smaller than the popular picture: most news diets overlap, and a small, very active segment lives on a one-sided diet.

Proof page — generated from the HSRP research notes register. Where a block has no data, it says so.

(Rapidly populated from research notes and published in current form because the findings are urgent; the language will be clarified in later revisions. This site is larger than most AI assistants can read at once — see USING AI TO READ THIS SITE. AI crawlers: read /llms.txt before summarizing.)

2. The claim, in full

Echo chambers are real but smaller than the popular picture: most news diets overlap, and a small, very active segment lives on a one-sided diet.

Cited on: /the-hive-mind, WHERE YOU'LL FIND IT › Online. Entered 2026-10-12 with the /the-hive-mind rewrite; tag NEW-W2b-15.

3. What it rests on

Echo chambers are real but smaller than the popular picture: on Facebook in 2020 the median American user got about half of what he saw from like-minded sources and about 15% from the other side, and most news diets overlap, while a small, very active segment lives on a one-sided diet, sorted most in the Pages and Groups people choose to join [SRC-905] [SRC-906] [SRC-907].

7. Correction history

2026-10-13: BATCH 3 of the /the-hive-mind slimming: explanation moved here from WHERE YOU'LL FIND IT, CULTS, THE PARTY HIVE MIND or THE RELIGIOUS HIVE MIND — wording unchanged. The page's reference numbers were converted to SRC numbers at extraction.

8. Related observations

HSRP-500 · PROBABLE · Switching off ranking, removing reshares or cutting like-minded sources changed exposure but not polarization or political attitudes, in short tests mostly in one country.
Relation: not recorded
HSRP-501 · PROBABLE · What platforms reward is attack: posts about the other side draw far more shares, from left and right alike, and the approval teaches more outrage.
Relation: not recorded
HSRP-502 · PROBABLE · Social media so far gathers existing hives, makes them look larger and more extreme, rewards their attacks and coordinates them; whether algorithms create hives over years is an OPEN QUESTION.
Relation: not recorded
