Pre-attentive processing is our ability to instantly, subconsciously pull information out of an image. An example is finding a red circle within a cluster of blue circles. (Image: Healey; link below.)pic.twitter.com/QKgdOgqFE1

Above, you don’t have to focus on each individual circle to see if it’s red or blue—the red one just “pops” out. Much like Google’s earliest designs with colored boxes for ads.pic.twitter.com/jSxuAkiqOs
Pre-attentive processing is extraordinarily effective, but ONLY if there’s a single visual variable such as a distinguishing color or shape. So even as the ad label grew more subtle in past redesigns, it was still (arguably) pre-attentive and hence fast.pic.twitter.com/AAaO0NSHiR
But when you mix colors and shapes, say to show colorful favicons in the same spot as the “ad” label, you break pre-attentive processing. It’s now much harder to find the red circle.pic.twitter.com/VGrewnl5X6

Similar to the misdirection techniques employed by software sites and their download button.pic.twitter.com/w9HaMuHhTa
@DuckDuckGo for ever
They used to have a great search engine, then they changed to yahoo, and results were crap.
So, can we claim it to be “evil”?
