After comparing my father's photos with those of his brother's in Tuesday’s post, Buster vs. Dad – An AI Perspective, I’ve found myself on a new mission—revisiting my collection of unidentified photos with help from AI.
This photo of two young men was shared by a cousin, who identified them as Floyd William Thompson (1889-1968) and one of his brothers.
Floyd had five brothers:
- Aaron Whitney Thompson (1886-1964)
- Claud Clarence Thompson (1891-?)
- Edgar Richard Thompson (1896-1983)
- Walter Alexander Chisum (1876-1816) [half-brother]
- Philip Louis Chisum (1881-1962) [half-brother]
I uploaded the photo to OpenAI’s ChatGPT along with at least one confirmed image of each brother—except Claud. I’ve never come across a photo of Claud Thompson. I also provided their names and birth years. I've learned that AI performs better when I include some background information.
AI Analysis
I first used ChatGPT 4o to upload photos and ask questions. I really liked this table created by AI. It made me consider details I might have overlooked.
This model confidently identified Floyd as the standing figure, citing specific facial features and stance as evidence.
However, this AI automatically assumed the standing boy was older, despite the possibility to the contrary. It also made questionable observations, like claiming the seated boy had "less prominent ears"—which contradicts what's visible in the photograph.
When I challenged certain conclusions, the AI adjusted its analysis to accommodate my input rather than defending its position with evidence. For example:
- With the initial comparison, AI wrote, "The seated boy is likely another Thompson brother, but doesn't clearly resemble Edd, nor Floyd in his later years."
- When discussing birth years, AI responded, "Based on appearance, Claud Clarence Thompson (b. 1891) is a more likely candidate than Aaron."
- When reminded that no photos of Claud existed for comparison, the AI response was "The seated boy now appears to be Edgar Richard Thompson rather than Claud."
This inconsistency prompted me to seek a second opinion from a custom GPT specializing in historical photo analysis, Mark Thompson’s Historical Photo Analyzer, available through OpenAI’s ChatGPT platform. This consultation provided excellent historical context and thorough comparative analysis, but yielded the exact opposite conclusion, identifying Floyd as the seated brother.
Given the conflicting results, I decided it was best to conclude this AI comparison. Moving forward, I'll continue using AI as a supplemental tool. In my last post, Buster vs. Dad – An AI Perspective, AI did an excellent job pointing out similar features that could be easily observed. Not so much with this project. What I learned is that AI can help me see things I might overlook, but it is not a replacement for my intuition, family knowledge, or careful comparisons.
For now, I will share this post with my family and on the Erath County Genealogical Society Facebook page, in the hope of gaining more insight from others who might recognize the faces or have additional knowledge about this family.
