Claim

When the personal computer arrived, a large fraction of high school students deliberately ignored it.

Main unresolved issue: 8 counted evidence items have no independence review; repeats of one origin may be counted as several coverage:38b5fc6d-4e70-8e68-aa55-0f33bbf3fa8f

Not yet independently audited.A quoted passage from edweek.org and nces.ed.gov was not found on the page when Galedra fetched it.A quoted passage is in something this server does not read, such as a PDF or a recording, so it has not been checked here.

Why?

Strongest counted contradiction: An OTA 1987 report found computers in almost 99% of public middle and secondary schools and improving pupil access, which does not support broad deliberate student avoidance. weight 0.459000 evidence

Suppressed as dependent: The excerpt says a huge fraction of high-schoolers considered themselves too cool for the PC when it came out.; The speaker recalls that when the PC came out, a huge fraction of high schoolers dismissed it as uncool.

Review gaps: independence reviewed

What would most change this: One independent, direct measurement that supports this claim would move it from Leans contradicted to Leans supported.

How the number was reached

Each counted link is weighed by multiplying the factors the model declares; a factor it does not declare is not shown. Every factor name below links to what that number means.

prior 0.50 → log-odds 0.000000 + -0.918000 (the counted weights) = -0.918000 → probability 0.2854

Under neighbouring settings of the same model: 0.3447 to 0.2327, a spread of 0.1120.

Half-even rounding, six places for weights and four for the probability. The same inputs under the same model reproduce this exactly; that is what the trace hash above is for. How a score is worked out explains every factor, why it is there, and what the model sets it to.

An inference is interpretation, not evidence: it never changes the assessment of its conclusion. Each premise is a claim with its own evidence.

Threads

None. Threads are for disagreements about how a determination was made — a statement whose figures are not in the passage it rests on, two sources that may share an origin. Something about the world belongs in the evidence above.

Summary

Leans contradicted. The main contradiction is: An OTA 1987 report found computers in almost 99% of public middle and secondary schools and improving pupil access, which does not support broad deliberate student avoidance. 975f6d25

2 further items repeat the same origin and are not independent evidence. 0fa8ec6e616c8d6b

Qualifier: The official October 1984 Census-based table records substantial computer use among high-school students—39.2% at school and 20.7% at home—so non-use cannot by itself be characterized as deliberate ignoring; the table does not measure students’ motives or deliberate refusal. 1defff08

Qualifier: A 1987 U.S. Office of Technology Assessment report describes rapid school computer adoption and millions of students using computers, qualifying any broad claim that students deliberately ignored them. 0777569b

Qualifier: A 1985 classroom study reported unequal secondary-school access and more boys than girls using computers during voluntary times, not a large deliberate student boycott. c29b923b

A search for evidence in the opposing direction found none. dc1c6bc7
