It's such a little thing but while reading the opinion I see that the court (Kagan in this case?) makes a factual claim it provides SOURCES.

"Modern cell phones, we observed a dozen years ago, are “such a pervasive and insistent part of daily life that the proverbial visitor from Mars might conclude they were an important feature of human anatomy.” Riley v. California, 573 U. S. 373, 385 (2014). Since then, the percentage of Americans who own smartphones has only increased. To- day, more than nine in ten Americans own a smartphone. See W. Bishop, Pew Research Center, Mobile Fact Sheet (Nov. 20, 2025) (91%); compare A. Smith, Pew Research Center, Smartphone Ownership—2013 Update (June 5, 2013) (56%)."
The surprising bit is that 10% of Americans DO NOT own a smartphone. That must be exceedingly difficult. Increasingly everyday activities require them, without fallbacks. I presume those numbers exclude children, and then if you account for the infirm, it wouldn't surprise me if we started to get to universal levels of ownership.
Tbh it feels quite performative, giving an air of rigor to the what often feels like post hoc reasoning and selective application of precidence and case law...
Most SCOTUS opinions are rigorously sourced. They’re usually also well argued. The recent spate being an exception, in particular anything written by Alito.
