Who Is Challenge?


By default, humans are not up to a challenge because it goes against their programming. Challenges not only involve change but also a risk of failure - a double whammy enough to keep most humans in their comfort zone.

Why humans hate change
The brain makes up only 2% of your body mass and yet uses about 20% of your energy. Because of this, human brains have had to evolve to be as energy efficient as possible and one way it does this is by forming neural pathways when you begin to learn something new - habits. How many times have you left the house or your car wondering whether you locked the door? This is because the process of locking the door became a habit and you do the action unconsciously. Things that you do unconsciously consume less energy. You feel mentally drained the first time you try riding a bicycle but after practice it becomes effortless. It’s this “mental drain” expectation when a change comes along that prevents you from taking on a challenge. Your brain tells you “change is bad because it uses up too much energy - don’t do it!”

Why humans fear failure
One of the reasons why humans still exist is because of our built-in fear mechanism. Many eons ago when we heard a rustle in the bushes, the fear response activated is what contributed to keeping us alive - that rustle in the bushes could have been a predator that wanted us for dessert. 
The fear response generated by the area in the brain known as the Amygdala gave us stress and anxiety which prompted a response that kept us alive. This is known as the Fight-or-flight response which increases our heart rate and blood flow to our muscles, causes us to hyperventilate (for the extra needed oxygen) putting us in a state where we decide whether we want to fight off the potential threat or run away from it (flight).

However, while this fear response was great for making sure we didn’t end up being eaten when we were hunter-gathers, the same fear mechanism still exists hardwired in our brain and activates every time we come across a situation where failure is a possible outcome. This hardwired fear response tells us that taking risks is bad - don’t wait around to see if that rustle is a predator - just run!

Each time we avoid change, each time we step away from a challenge, we end up strengthening the default hardwired neural pathways - this is how we end up with a stubborn personality and stuck in a rut - you are not going to get to where you want without taking risks.

Challenge is a symbol and a reminder of why we are wired this way and that we have the ability to re-wire ourselves to take risks, embrace change and never fear failure. A “failure” is just another term for a step to success - without failure, there is no success.

Before You Buy (Overview)

Smart Doll’s are crafted with care, intention, and a strong commitment to quality—but they are not designed to be everything for everyone. Since all sales are final, we ask that you take a moment to understand what makes our products unique before placing an order.

The photo grid below highlights common concerns we’ve seen from customers *after* receiving their Smart Doll—despite these traits being explained throughout our website. Our goal is to help you make an informed decision upfront rather than face disappointment later.

The first row covers wig-related traits, the second explains details of our slush-cast vinyl body and frame, and the third focuses on the intentional asymmetry in our face design. A brief overview follows the grid below:

Wig Characteristics

Smart Doll wigs are shaped by hand—not by mold—so variation is natural. You may notice differences in thickness, alignment, or shape from one wig to the next. Some may appear “balding” in spots or shed small amounts of hair when first opened and with continued use. Tight fits can leave marks on the head, and a bit of styling oil residue is also expected. (images 1 - 4)

Slush-Cast Vinyl Body & Frame System

The Smart Doll body is made from sofubi (soft vinyl) using a hands-on process called slush casting. This naturally results in variations such as asymmetry, flow lines, air bubbles, and differences in surface texture. The head cap may not match the body color exactly or fit perfectly. These traits are inherent to working with soft vinyl and are part of the handcrafted nature of the product. (images 5 - 8)

Intentional Asymmetry in Face Design

Just like real human faces, Smart Doll faces are intentionally asymmetrical. From the 3D sculpt to the final brush stroke, no two are exactly alike. Hand-painted features such as eyeliner, lashes, and blush will differ slightly in size, shape, and placement. If you’re seeking factory-perfect, machine-printed symmetry, a different brand may be a better fit. (images 9 - 12)
