This is the Müller-Lyer illusion. You’ve probably seen it before: it consists of two lines, each with forked ends. The middle portion of the top line looks longer than the middle portion of the bottom line. However, when you measure the length of each middle portion, they are the exact same length.
The moon illusion
The previous examples are all pretty contrived. They were designed to take advantage of how your brain perceives light and shadow. But there are other, more subtle examples that you experience every day.
Next time you’re outside at night, take a look at the moon. How big does it look? If the moon is near the horizon, it will look relatively large and close. When it’s high in the night sky, it will look small and far away.
But no matter where it is in the sky, the moon is always the same apparent size — if you held a ruler at arms length, it would measure the same throughout the night! You don’t even need ruler to check: take a sheet of paper and roll it up into a narrow tube. Point it at the rising moon and adjust the tube’s size until it’s a little larger than the moon’s diameter. Tape the tube so it stays the same size and look at the moon again a few hours later. You’ll see that it fills the same space. Knowing that the lunar orbit was circular (and not elliptical, as it first appears) was the key to understanding how the moon interacted with the Earth’s oceans to create the tides. After learning how to see the moon’s orbit, scientists could make accurate forecasts of high and low tide (useful for shipping goods) and create accurate calendars (useful for planning military maneuvers).
How designers see
These phenomena show the difference between merely seeing things and knowing how to see things. There are lots of things that you see every day that you merely see; there are some things you’ve learned how to see.
This is how professional creative workers (digital product designers like me, for example) do our jobs. We don’t have a mystical sixth sense, some X-ray vision that allows us to access hidden insights and information. Through thousands of hours of experimentation and study, we’ve learned how to see the kinds of things we are asked to design.
Take websites, for example. The average person sees nearly 100 pages every day. Despite such familiarity, the average person hasn’t learned how to see websites. Their impressions and beliefs of web design are susceptible to bias, such as banner blindness. Banner blindness is the phenomenon where website visitors subconsciously ignore content in certain positions (at the very top or in the rightmost column) or sizes (wide rectangles) because they resemble advertisements.
My experience as the design director of wsj.com taught me how to see websites through the lens of banner blindness. Advertisers often wanted their ad to be placed in a prominent position at the very top of the homepage, assuming that would get the most attention. However, I knew that other, smaller placements further down the page performed better. One treatment in particular, called a membership tile, was our best-performing ad day after day; it was placed near other articles to avoid the banner blindness effect.
Despite my knowledge and experience, and even armed with the data to back up my claims, it was still difficult to convince stakeholders of banner blindness. It was like telling someone that the moon is the same apparent size throughout the night.
How to learn how to see
Knowing how to see is a valuable but overlooked skill. No matter what it is you do for a living, learning how to see will improve your ability to make judgements and do impactful work. And it’s really quite simple:
Ask the stupid questions.
What we initially think are stupid questions often turn out to be informative and worthwhile. Asking them gives us the opportunity to explore and learn from conventional wisdom, and helps us take nothing for granted.
For example: why are links on the internet usually blue?
Seek multiple explanations.
It’s tempting to take the first plausible explanation of an observation as the truth. But don’t be content with a single story. By finding other explanations, you’ll either strengthen your initial understanding or discover an even better line of reasoning.
Maybe links are blue because an engineer creating the first web browser thought it should be blue, and that was enough to create a standard. But maybe they’re blue because decades of research has shown that blue is the color that our brains can locate fastest on a colorful page.
Challenge your own assumptions.
The biggest difference between merely seeing from knowing how to see is understanding that our brains can (and often do) deceive us. That means that our assumptions are wrong much of the time. Being willing to be wrong — that is, being humble about our beliefs — makes it easier to replace seeing with knowing.
Originally, links were blue simply because the early developers of browsers thought it looked good. But accessibility research has shown that blue is, in fact, a good color for links. Joe Clark explains in Building Accessible Websites:
“Red and green are the colors most affected by color-vision deficiency. Almost no one has a blue deficiency. Accordingly, nearly everyone can see blue, or, more accurately, almost everyone can distinguish blue as a color different from others.”
Links on the internet have remained blue by default, but most designers and developers aren’t just following tradition. They understand the important accessibility concerns of technology, and constantly revisit defaults to create the best experience for the most users.
When you engage your personal designer, make decision first on what you like from his/her works. You should fascinated by his/her portfolio and experience, and, follow him/her when fix a design line. Because he/she is a designer, not simple executive.
Will you manage Mr. Valentino as an executive?
