Weird viral photo of Adele's face exemplifies the phenomenon called the Thatcher effect
The 42-year-old optical illusion is still astounding people.

Prepare to get Thatcherized.
It seems that Adele is going viral once again. Perhaps you’ve seen the image in question previously (it seems to make the rounds every couple of years). But in case you missed it—it’s Adele’s face. Normal, just upside down.
Only it’s not normal. In fact, when you turn Adele’s face right side up, what you notice is that her eyes and mouth were actually right-side up THE ENTIRE TIME, even though the entire head was upside down. So when you turn the head right side up, the eyes and mouth are now UPSIDE-DOWN—and you can’t unsee it. Do you feel like you're Alice in Wonderland yet?
Just wait. Things get even more fascinating. Especially because this optical illusion is over 40 years in the making.
Below you’ll find the Adele photo in question. Go ahead. Take a look at it. Then turn the image upside down.
Can't. Unsee.
Crazy right? And just a little terrifying?
As the Facebook post explains, this mind-boggling image highlights a phenomenon known as the Thatcher effect. Our brains, so much more used to recognizing faces that are right-side up, have difficulty detecting specific changes once a face is upside down.
Seeing that everything is more or less where it should be, our brains don’t notice anything out of the ordinary in Adele’s face until we turn her face back to a normal position.
The Thatcher effect got its name from British Prime Minister Margaret Thatcher, on whose photograph it was first demonstrated back in 1980 by Peter Thompson, Professor of Psychology at York University.
This demonstration was one of the first to explore just how facial recognition works, and certainly the first to suggest that humans (and monkeys, it turns out) process faces on a more holistic level, rather than by individual components like lips and eyes. Since its publication, there has been a wealth of research exploring how our brain takes in both subtle and striking facial configurations.
Funny enough, it was once believed that this illusion only worked on the Prime Minister’s face. But as Adele has proven, anyone can be Thatcherized.

There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.

Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
