VI is useful to get a "general picture" of the person you're typing. It's simply not possible to accurately type the person using photos alone. I'd argue that it is often possible to VI someone through video, but one might argue that this isn't just typing someone by VI - it's also evaluating their personal beliefs and opinions (if indeed they are discussing these). Those who type people solely based on VI are those - like Ganin - who believe that you can look at the physical make up of a person and know exactly what type they are. This is bullshit. It takes no account of a person's mental life into account. Ganin would type a wax model a certain type, or a brain-dead individual. I think we all agree what crap that is.
