Completed demonstration records

See how a Proofhouse conclusion is built.

Eight examples—one for every examination type—show the distinction between a file being genuine, a claim being supported, and material being presented honestly.

These are clearly labeled demonstration scenarios showing how the examination record works. They do not represent private user submissions.

Demonstration 01

Reposted storm photograph

Photographs & Screenshots

Question: Does this image show the storm named in its caption?
Finding: The image itself is genuine, but an earlier publication places it at a different event and date.
Confidence: Strong
Limits: The first photographer cannot be established from the demonstration copy.

Demonstration 02

Short speech clip

Video

Question: Does the clip preserve the speaker’s complete statement?
Finding: The frames are continuous, but the excerpt removes the qualifying sentence immediately before it.
Confidence: Strong
Limits: Authenticity of the original recording is outside the supplied excerpt.

Demonstration 03

Interview excerpt

Audio

Question: Is the apparent pause part of the original conversation?
Finding: A discontinuity and transcript comparison support that two separate passages were joined.
Confidence: Moderate
Limits: The editor’s purpose cannot be inferred from the edit alone.

Demonstration 04

Circulating institutional notice

Documents & PDFs

Question: Was this PDF issued in the form being shared?
Finding: The contact block conflicts with the institution’s archived notice and the PDF records later editing software.
Confidence: Strong
Limits: The demonstration does not identify who produced the altered copy.

Demonstration 05

Health-information article

Web Pages & URLs

Question: Do the cited sources support the headline?
Finding: The cited study reports an association in a narrow group; the headline presents it as general causation.
Confidence: Strong
Limits: The underlying medical question requires evidence beyond one study.

Demonstration 06

Reused wildfire video

Social-Media Posts

Question: Was this footage recorded during the current fire?
Finding: Matching frames appear in an older news report from another region.
Confidence: Strong
Limits: The uploader’s knowledge or intent cannot be determined.

Demonstration 07

Historical quotation

Written Factual Claims

Question: Is the quotation reliably attributed?
Finding: No contemporary primary source has been located; the wording first appears much later.
Confidence: Moderate
Limits: Absence from reviewed sources does not prove the words were never spoken.

Demonstration 08

Public-opinion bar chart

Graphs & Statistics

Question: Does the chart fairly display the reported change?
Finding: The values are accurate, but a truncated axis visually enlarges a small difference.
Confidence: Strong
Limits: The demonstration does not assess the survey’s sampling method.
