This might be the worst possible way to measure the net throughput of conscious decision making I've ever seen. A wildly ecologically invalid, serialized discrimination task.
Now take someone navigating a social situation with three simultaneous participants, actively listening, coordinating body language, interjecting, responding to questions... and you have a human being operating at a "bitrate" of information that is so many orders of magnitude removed from this bullshit psychometry task as to prompt the question: "what the actual are they talking about".
Using a computer analogy to try to understand the brain functions is ok as long as we remember that the brain is not actually one of them. There have been different technological analogies throughout history including hydraulic systems, telegraphic and telephonic lines, all of them might seem comical today but they were the best explanation at the time, same will be in the future with ours, comparing something like the brain (or rather the whole living being) to a mathematical processing device is more than short sighted. We try to explain everything from the engineering point of view by isolating things but that’s not how life or the universe works.
