The thing I love about Jakob Nielsen, as opposed to Edward Tufte (though I also love Tufte's stuff) is that he never just tells you "this is how to present this information"; he backs it up with real studies with real people that track eye movements and actions and records what people learn and retain. It's more than just truthy; it's science.
