This illusion is pretty fascinating. It might actually point the way to a new discovery. The color constancy effect has been known for a long time, and there are many illusions around that show (to the same viewer) how a colored surface can appear to be one hue or another depending on the circumstances.
This week before Easter gives me cause to pause and reflect. Haven't men always failed to trust women, because somehow there is an innate belief that women are less trustworthy? But I'm reminded on Easter that Jesus did. And it tells me that somehow, when it comes to bearing witness to Him, He trusts me too.
Seeing and believing are not synonymous, as optical illusions can be rooted more deeply in cultural beliefs. Half of the difficulty with empathy lies in the fact that we can never truly know how others see the world, either literally or psychologically, but as we grow older and more settled in our worldview we tend to assume otherwise.
