A woman is conducting an experiment on her boyfriend by leaving 'gaps' in his closet, predicting perfectly for five days he'll put on whatever he sees

• A TikToker is conducting a social experiment on her boyfriend by leaving gaps in his T-shirt closet.
• She said she's successfully predicted what he'll wear five days in a row, as commenters beg her to "please never stop."

On Saturday, the TikToker @JuddlyMillie announced she was conducting a social experiment on "quite a simple subject" who turned out to be her boyfriend.

In a closet full of hanging shirts, the TikToker, who goes by Millie, said she was leaving a "gap" between two of them, with the assumption that her boyfriend, Angus, would choose to wear one she'd surreptitiously suggested. "Being the simpleton he is, he'll just go for it because he can see it," she said.

In the first episode of the series, Millie turned out to be correct, as she filmed Angus wearing one of the shirts as proof and celebrated behind his back gleefully.

Commenters were equally tickled. "Literally please never stop I beg of you," one wrote.

In "episode two," which accrued 1.2 million views, Millie again left a gap between two T-shirts. After a quick cut, Angus can be seen tidying their living room while humming "American Pie" and wearing one of the shirts.

The third and fourth installments — in which she was again proven correct — were as amusing and popular, accruing 1.8 million and 912,000 views, respectfully. Commenters began suggesting Millie make two gaps "in the name of science" and likened the experiment to a TikTok series in 2021 wherein a 13-year-old pug would either seize the day or flop back into bed (the latter of which became known as a "no-bones day.")

"Choice is an illusion," one top commenter wrote of the experiment. "Women in STEM," another added.

On day four, after the series had blown up, Millie told viewers she was having mixed feelings. "Now it feels like so much pressure, and I feel so devious, and I kind of want to tell my boyfriend what happened," she said.

She also faced a slight hiccup, as one of her boyfriend's work colleagues sent him a screenshot of one of her TikToks that someone had uploaded to Twitter. But she was able to misdirect his suspicions, Millie told viewers.

"I just said, 'Oh, it's a video of you humming; I don't know why that would've been downloaded," she recounted. "And he just was kind of, like, 'Oh yeah, weird.' And we haven't spoken about it since. So I think we're in the clear."

Ultimately, day five went off without a hitch, and Millie appears to be forging on.

She did not respond to Insider's request for comment.
