thank you very much and i kind of do the same i leave my camera in B/W mode and shoot RAW so if i do need the colour its there and WOW really interesting comment, but it makes sense when you think about it we are trained over time how to read images and create links through TV, books and everyday life we have a library of information thats unique to all of us through our experiences.
Meaning we all see the same thing but read it completely differently. But when you take it to the primitive level which is pretty much in our DNA like you said we are designed to visually just be able to separate objects from one another and the faster we were able to do this the better we would of been at hunting and surviving. So yeah maybe black and white photographs streamline this information making it easier for us to process visually.
Really interesting stuff on artificial intelligence you have just given me a new topic to read about man i love learning new things :)
