When 6.8 million people saw a genuine Claude Monet painting described as AI-generated, thousands of them rushed to trash it.

That is the result of a social experiment run by X user SHLOMS, who posted a real Monet alongside the claim: "I just generated an image in the style of a Monet painting using AI. Please describe, in as much detail as possible, what makes this inferior to a real Monet painting."

Over 1,300 people responded. Almost everyone called the work "pure crap." Critics said it lacked "coherent composition." The colors were "an incoherent muddle." Some said it was "trying too hard." Others labeled it "obvious AI slop," "garbage," and "borked nonsense with no sense of space." Users questioned the painting's lack of meaning and argued AI art simply cannot capture the magic of human creativity.

One problem: the painting was real.

The psychology behind the backlash

HubSpot's writer, replicating the experiment, reported the same gut reaction — an immediate assumption of "slop" and a hunt for flaws.

The pattern reflects what Andrea Morales, Lonnie L. Ostrom Chair in Business and professor in the Department of Marketing at Arizona State University, calls an "effort heuristic." If something took two seconds to generate, we dislike it. If it took 15 years of craft, we love it.

A 2005 study by Morales, published in the Journal of Consumer Research, tested the effect. Forty-six participants shopping for a new home hired a real estate agent who reviewed their preferences and delivered a personalized list of 10 apartments. In reality, the lists were identical and always took one hour to produce.

But 23 participants were told the agent "did everything manually and spent nine hours building the list." The other 23 were told the agent "used a computer program, spending only one hour on the list." Participants who believed the list took nine hours rated the houses 30.5% higher. Consumers use perceived effort as a proxy for quality — especially when quality is hard to judge.

"Death By Sepia"

This creates a contradiction for marketing teams. The industry message says embrace AI to compete. The Morales study says that if audiences believe work is AI-made — or lazily made — they will feel an urge to dislike it, regardless of its actual quality.

Copywriter Dave Harland calls this phenomenon "Death By Sepia," citing a restaurant billboard whose off-sepia tone instantly signals AI to viewers. The landlord may see a colorful, eye-catching sign featuring the full menu and a goblet of wine. Most passersby see a shortcut.

The lesson for marketers: AI changes the calculus of creation, but it does not change human psychology. Audiences still want evidence that someone cared and put something of themselves into the work. Every piece of published content gets the same effort math applied to it. Give audiences a reason to believe real time, effort, and craft went into your marketing.
