What is the “Small Error” Discomfort in AI Ads?

AI-generated images often contain subtle inconsistencies in finger counts, background balance, or eye direction. These minor flaws unconsciously register as unnatural, eroding viewer trust in the brand. In the JA Sagami case, the woman’s left hand and bag handle were specifically called out for distortion. Such accumulated errors make the core message harder to convey.

The JA Sagami AI Poster Incident and Farmer’s Criticism

On June 17, 2026, fruit farmer @farm_ichikawa from Ebina City posted about JA Sagami’s event poster on X. The poster, created with generative AI for a corn festival and community event, drew criticism: “A poster made by just clicking on a PC is far less effective than one photo taken directly in the field, even if it’s amateurish.” The post went viral, prompting discussions on AI usage and effectiveness. JA Sagami has not officially acknowledged AI use at this time.

Reactions on X: Both Agreement and “It Comes Across Normally”

Many X users echoed that “small errors create discomfort,” noting how distortions in fingers or tent patterns shift attention from content to whether it’s AI. Some defended it, saying it “comes across normally,” citing benefits for elderly audiences or cost savings. Others expressed disappointment over YouTube channels switching to AI illustrations and concerns about illustrator job losses. Overall, opinions were divided.

Why AI-Generated Images Create Discomfort: Technical and Psychological Reasons

Discomfort arises from prompt precision limits and training data biases, leading to inconsistent details like finger counts or shadow directions. Psychologically, humans possess an innate “AI detector” that diverts focus the moment AI is spotted. Hashout analysis points out that “once you notice it’s AI, the content stops registering.” In community-focused events, the sense of effort is crucial, making AI use potentially counterproductive.

Comparison with Real Photos and Hand-Drawn Illustrations

Aspect	AI-Generated	Real Photos	Hand-Drawn Illustrations (e.g., Irasutoya)
Trust	Prone to drop due to errors	High from direct capture	Consistent style builds familiarity
Cost	Low	Medium	High (artisan skill)
Message Clarity	Easily hindered by errors	Strong emotional connection	Impressive niche patterns
Brand Image	Risk of distrust	Conveys effort and warmth	Warm, approachable feel
Best Use	General promotion	Local community events	Friendly campaigns

Real photos taken directly in the field provide trust and closeness that AI often lacks. Hand-drawn illustrations offer consistent touch and avoid the unnatural feel of AI.

Future Challenges and Improvement Strategies for AI Advertising

Key challenges include detail accuracy and brand image mismatch. Recommended improvements include refined prompts, human final review, and hybrid use with real photography. Transparency about AI use is essential to avoid backlash from perceived concealment. For agricultural cooperatives, AI is convenient but this case encourages rethinking the original purpose of announcements. The key going forward is integrating human warmth alongside AI tools.
