There are a number of esoteric companies offering stickers that they claim can reduce the effect of unwanted electromagnetic fields (so-called electrosmog) on biological organisms in the near proximity of the electronic device (e.g. mobile phone). Backed up with scanty, if any, scientific evidence. And by scientific evidence, I mean a clear hypothesis, tests designed to isolate a single variable, and statistical results as opposed to pretty pictures. Well… here’s one company which has published some scientific findings regarding the effectivity of their products – and I commend them for doing so! Ignoring the fact that the leading scientist seems to have no credible research papers published to his name, let’s take a look at the results.

Test in 2011: this actually looks like they might be onto something. Not only a clear description of the test methodology, but also astounding results in section 4.3. To quote the conclusion: “The compensation potential is up to 100% for disruptions of up to 0,4 Microtesla, and beyond that 50%.” So there you have it: measured effectiveness of 50% for the claimed capabilities of electromagnetic field restoration.

Repeated test in 2014 (no idea if there were any ‘research developments’ on how to make that sticker ‘better’ between 2011 and 2014): forget that previous result. This repeated test shows that can nice results can only be achieved by selectively choosing measurement points to create a ‘positive’ conclusion. (More concretely: the sticker does have a minimal effect, which starts to be effective at a distance of 20 cm from your mobile phone, and not at the typical 1cm distance you’d hold a phone at when you talk on it.)

Surprise, surprise, it looks like the sticker makes very little difference after all!

  1. +Tom Nathe actually, there are other, less obstructive solutions – for example, wallpaper with conductive material arranged in special disruptive patterns suffices to block targeted wavelengths, or special paints and windows. These are often used in high-security areas with no-mobile-policies. But would most people really want that?
