Mirror tests we're now realizing are also very biased towards human perception and cognition, at least as they've historically been conducted.
A dog won't pass a visual mirror test for example, but they have zero issue with a scent based one.
Other times it may come down to more complex personal factors we're not yet fully able to understand. In the one test I was able to find involving Asian Elephants they tested 3 different elephants all from the same group/enclosure at the Bronx zoo. Only one of the 3 that were involved passed the test, but she passed it without leaving any room for doubt.
The fish in the article, cleaner wrasse, have specifically evolved to recognize colors or shapes that are out of place as that's how they identify the parasites they consume. Logically it makes sense they'd be better adapted to pass a visual mirror test than most animals.
If a small and otherwise unremarkable fish is able to pass the mirror test when conducted in a manner that coincides with how it has evolved to perceive the world then I don't have any trouble believing it's entirely possible many animals are capable of passing it. It's likely more a matter of how it's conducted, with the need for dedicated tests factoring in the animal's capabilities being the critical factor. If you think about it, if you were abducted by aliens and they had you try to identify yourself in a mirror that reflected infrared radiation, the spectrum they saw and perceived in, then you would fail too.
Oh they for sure care, just yesterday I was listening to a podcast and one of the ads was for Orlando. The theme of the ad? "Orlando is still great for gay people" They cited all kinds of statistics in an attempt to prove gay people should still visit and that it was a safe and fun place for them. They understand how critical those DINK tourists are, especially when you already have a lot of infrastructure and investment in attracting and serving them.
DeSantis doesn't care, but I promise you that lots of conservatives on the ground will start caring when their business traffic starts to choke off. Conservatives retire to Florida, but I'd imagine liberals make up at least half of the tourists between spring break, nightlife/LGBTQ hotspots, and how "woke" Disney has become.
Florida's current economic landscape is only possible due to tourism money, and once that reality becomes clear people are suddenly going to become far less concerned with non economic issues. Even the promise of tax cuts won't work when entire industries see their revenues drop by meaningful %'s.
I'm from Kansas, I know what it looks like and feels like to live in a conservative economic death spiral. The reality is you have to let it start getting worse before people take it seriously and put a stop to it. Even the conservatives here voted out Brownback after he started gutting every maintenance, service, and school budget in a failed attempt to balance his tax cuts. All those people who treat politics as a game get real serious once it hurts them directly, but until then I'm not sure there's an effective way to reach them.
