Authenticity just became an even bigger selling feature.

A 2025 arXiv study found that people (and even AI tools) can only tell fake product reviews from real ones about half the time.

That’s no better than a coin toss.

And it means the entire review economy is breaking.

For product makers, this changes how trust is built.

Buyers are looking less at stars and more at signals of real humanity.

So design for proof, not perfection.

Show verified-user badges prominently.

Offer quick video testimonial creation.

Encourage photos, timestamps, and posts that look messy, not polished.

The more your product feels human, the more it reads as trustworthy.

And when every other brand leans on generic “5-star” grids filled with AI text, you’ll stand out by doing the exact opposite … making your proof clearly from real humans.

Because with multiplying fake voices, authenticity sells more than ever.
