As someone with professional experience in photography and a masters in design – I think this piece is seriously lacking.
First – the photo that is used as "evidence" caught my eye quickly because it is clearly poorly processed/improperly exposed. There is no black point and that's a bad thing for the image; which leads me to say – you can't make the sweeping generalization that black is always bad. It's not – and the work of one pop art painter and a bad bit of photography isn't substantiated proof.
If you want to actually make something meaningful out of this, you'd actually push hard on the idea that too much contrast is a bad thing. Black isn't bad. Heavy contrast can be. Instead, get down to the root reasons that we have issues with contrast – in short, we're wired to notice differences in color or brightness than we are for absolute values of color or brightness. As such, it's not about one color, it's about the contrast.

Both of those do a much better job at explaining the hows and whys of the average person's visual perception.
