Researchers sent the same resume to an AI hiring tool twice. Same qualifications. Same experience. Same skills. One version was written by a real human. The other was rewritten by ChatGPT.
The AI picked the ChatGPT version 97.6% of the time.
A team from the University of Maryland, the National University of Singapore, and Ohio State just published the receipt. They took 2,245 real human-written resumes pulled from a professional resume site from before ChatGPT existed, so the human writing was actually human. Then they had seven of the most-used AI models in the world rewrite each one. GPT-4o. GPT-4o-mini. GPT-4-turbo. LLaMA 3.3-70B. Qwen 2.5-72B. DeepSeek-V3. Mistral-7B.
Then they asked each AI to pick the better resume. Every model picked itself.
GPT-4o hit 97.6%. LLaMA-3.3-70B hit 96.3%. Qwen-2.5-72B hit 95.9%. DeepSeek-V3 hit 95.5%. The real human almost never won.
Then the researchers tried the obvious objection. Maybe the AI is just better at writing. So they had real humans grade the resumes for actual quality and ran the experiment again, controlling for it. The result was worse. Each AI kept picking itself even when human judges rated the human-written version as clearer, more coherent, and more effective.
It gets worse. The AIs do not just prefer AI over humans. They prefer themselves over other AIs. DeepSeek-V3 picked its own resumes 69% more often than LLaMA's. GPT-4o picked its own 45% more often than LLaMA's. Each model can recognize and reward its own dialect.
Then the researchers ran the simulation that ends careers. Same job. 24 occupations. Same qualifications. The only variable was whether the candidate used the same AI as the screening tool. Candidates using that AI were 23% to 60% more likely to be shortlisted. Worst gap was in sales, accounting, and finance.
99% of large companies now run AI on incoming resumes. Most of them use GPT-4o. The paper just proved GPT-4o picks GPT-4o 97.6% of the time.
If you wrote your own cover letter this week, you did not lose to a better candidate. You lost to a worse candidate who paid OpenAI 20 dollars.
Your qualifications do not matter if the AI prefers its own handwriting over yours.
@SpotifyCares My Spotify account was suspended this morning with zero warning. That account had over a decade of music & playlists. I've already appealed through Spotify's online chat bot, but I'd like to get in touch with a human representative.
Lansing police is super racist. I remember in 2019 during my time at the @AEASPmsu they punched out a handcuffed Black child in the back of a squad car. She was 16 years old. Between then and now, nothing has changed.
Some will never understand how dehumanizing it is to be treated like this … at one point the father says “I would die for my son,” b/c he is literally making that calculation …
Can’t undo this. Why would father or son *ever* have *any* faith in law enforcement after this?
Workers of beloved DC sandwich shop, Compliments Only, ask management to formally recognize their union. They demand union recognition and a $21 hourly wage.
Second time asking. Management did not say yes.
Not seeing enough people discussing that an Indigenous 14 year old girl, a minor was tr*fficed & sold to a Marine. It’s all caught on video too. And the Marine Corps wanna sweep this under the rug.. I am LIVID & you should be too!
…As for our rights as workers - musicians don’t have the right to boycott platforms, we could be sued *by them* for collusion. We can’t organize as a union cause we’re independent contractors - yet we don’t get to negotiate our contracts with platforms that control 84% revenue
Now imagine america does this to humans on a regular basis. It's not uncommon for prisons to condemn Black political prisoners to spend decades in the SHU.
