Beauty makes people feel good. That’s a great thing. Even if we don't agree on a specific features or characteristics we can still talk about the effect.
Here’s my theory: Beauty is a state in which there are no evident distractions or problems, combined with some elevating quality. It’s a harmonious balance in which nothing stands out to be removed, added, or changed. A state of beauty allows me to relax and focus. It’s the perfect backdrop for productivity; non-intrusive but stimulating.
Compare that with Familiarity, which can yield some of the same benefits; it’s relaxing, safe, and non-distracting. But it misses the best effects – the stimulation and psychological lift. If the workplace doesn’t deliver that special benefit, there’s one more reason for your best employees to find other places to work.
