Saw this one before, the message is good but I dislike the use of a box at all here because the analogy is still weird. I like to think of it as an equalizer, traits are at different volumes and gains like the different frequency ranges of sound going through a sound system simultaneously. (Think bar chart for alternate example.) Different traits manifest differently, i.e. perseverance, stimming, sensory sensitivity, monotropism, special interests, etc.
Tangentially on the same topic, I dislike the term "on the spectrum" because this article's reasoning. You are not sitting atop a one dimensional number line. You ARE the spectrum, and your spectrum "settings" differ from that of others, though only to a certain extent (or otherwise Autism would not exist)
