Video Introduction to ROI Analyses

About forty years ago certain persons went up to Laputa, either upon business or diversion, and upon their return began to dislike the management of everything below, and fell into schemes of putting all arts, sciences, languages, and mechanics upon a new foot. To this end they procured a royal patent for erecting an Academy of Projectors in Lagado. Every room hath in it one or more projectors. The first man I saw had been eight years extracting sunbeams out of cucumbers.

--Swift: Gulliver's Travels, Part III, chs. 4-5

I'm updating my videos on fMRI basics, starting with ROI analysis. This is low-hanging fruit, yes, but delicious fruit, fruit packed with nutrients and sugars and vitamins and knowledge, fruit that will cure the scurvy of ignorance and halt the spreading gangrene of frustration.

In these videos you will observe a greater emphasis on illustration and analogy, two of the most effective ways to have concepts like ROI analysis take root inside your mind; to make them have a real, visceral presence when you think about them, and not to exist merely as words that happened to impinge on your retina. These videos take longer to make, but are all the more rewarding. And if they help you to think differently than you did before, if they help you, even without my knowing it, to see the world as I understand it, then I will have taken a significant step toward fulfilling my purpose here on this earth.
