Luka is the editor of Analysis of Fear. Nobody here buys or tests products: each article is built from manufacturer specifications, manuals and warranty terms, published standards, regulator data and recall notices, and every figure links to its source. First drafts are produced with AI writing tools; Luka checks them against those sources, edits them and signs off before publication, and handles corrections sent to support@analysisoffear.com.

Fountains attract some cats to drink more, though the hydration studies are mixed. They also grow biofilm in places you cannot see and fail when the pump silts up — which is a weekly job, not an occasional one.
SPF 50 is tested at 2 mg per square centimeter. Studies of real use repeatedly find people apply a quarter to a half of that — and protection falls at least as fast as the amount does.
Cartridge handles are given away because the cartridges are where the money is. Over ten years the difference between systems runs into hundreds.
The underlying science is real and the consumer devices are frequently far weaker than anything tested. The gap between the study and the mask is where the money goes.
The membrane almost never fails. What fails is the treatment on the outer fabric, and once that goes the jacket stops breathing and your own sweat condenses inside it.
The number on the bag is usually the limit rating — just warm enough curled up, not comfortable — and it assumes an insulated pad you may not have bought. Both mistakes are made on the same purchase.
The words are used interchangeably in shops and they mean different things. A filter stops bacteria and protozoa; viruses go through it. Where that matters depends on geography.
Monitors are sold on refresh rate and resolution. What you notice after a week is the panel: how the corners look, whether blacks are gray, and how it handles a window at an angle.
RAID protects against one specific failure: a drive dying. It offers nothing against the far more common ones — deletion, corruption, ransomware — and rebuilding it is when the second drive tends to go.
Switch specifications are precise, comparable and nearly useless for prediction. Two switches with identical numbers can feel completely different, which is why hot-swap sockets matter more than any spec.
The connector was standardized. Almost nothing behind it was. Two identical-looking USB-C cables can differ by 180 watts of power and a factor of eighty in transfer speed.
The number on the box is measured at 3.7 volts inside the pack. Your phone charges at 5 volts or more. That conversion, plus heat, eats about a third of the capacity before you see any of it.
