The McGurk effect and what it tells us about our noetic faculties

Here is an excellent example of the McGurk effect:

My interpretation of this effect is based on the physics of both sound and light waves. Based on Shannon’s theorum, light carries more information than sound so it makes sense that our minds would, when presented with conflicting information. So it is understandable why many people operate on the principle of “seeing is believing”. However the McGurk effect should serve as a warning to us that when faced with problems of interpreting information, what we are seeing may be masking the truth of what we are perceiving.


Global data storage calculated at 295 exabytes. Still less than the average cell.

Recently, the BBC cited a study which estimated the total amount of data stored by humans to be 295 exabytes

The study, published in the journal Science, calculates the amount of data stored in the world by 2007 as 295 exabytes.

That is the equivalent of 1.2 billion average hard drives.

As impressive as this sounds, nature is more impressive still. The report continues

These numbers may sound large, but they are still dwarfed by the information processing and storage capacity of nature.

“The Human DNA in one single body can store around 300 times more information than we store in all our technological devices” according to Dr Hilbert.

How much data is estimated to be in 1 cubic centimeter of DNA? About 108.420217 exabytes.

Its also estimated that the human body processes about 430 zettabytes/day.

And we are expected to believe that all of that precision machinery happened by unguided, unintelligent processes.

Like magic.

Bonus: Here is a story by the Washington Post on the same topic.

But Hilbert offers a humbling comparison. Despite our gargantuan digital growth, the DNA in a single human body still stores far more information – and a single human brain computes far more calculations – than all the technology on Earth.

“Compared to Mother Nature,” Hilbert said, “we are humble apprentices.”

I think he misspelled God there.
