When most people are presented with a report of something having happened, they tend to evaluate it in one of three ways:
* The person is telling the truth and is reasonably accurately reporting the situation
* The person is telling the truth, but is mistaken about what happened
* The person is deliberately lying, and the situation did not happen
There are a number of factors that weigh into that evaluation.
One of them should not be the "extraordinariness" of the claim, in my opinion.
Marcello Truzzi famously said that "Extraordinary claims require extraordinary proof." He was quoted by Carl Sagan, so some attribute the phrase to the astronomer.
For me, science should mean that you evaluate all claims without regard to previous assumptions.
What makes an extraordinary claim more difficult to accept is that every claim of a sighting (for example), is a compound claim, having several elements.
If someone says to you, "I saw a horse in a barn," there are several elements:
* Horses exist
* Barns exist
* Horses can be in barns
* Horses can be seen
* The person in front of you can see
* The person in front of you could have been in a barn when a horse was there
Most people have already filed the first four above in the "true" category in their minds, so the claimant doesn't have to prove them. The odds are that the fifth claim is true, so for most people, it would come down to the sixth.
On the other hand, if someone said, "I saw a Bigfoot in a SmartCar," there would be more elements of the claim you might not already accept:
* Bigfoots exist
* SmartCars exist
* Bigfoots can be in SmartCars
* Bigfoots can be seen
* The person in front of you can see
* The person in front of you could have been where they could see a Bigfoot in a SmartCar
If you do not accept the first claim, you could still evaluate the person as honest but inaccurate. It could have been someone in a costume, for example.
I'm bringing all of this up because the basic claim in The Ancient Giants Who Ruled America: The Missing Skeletons and the Great Smithsonian Cover-Up by Richard J. Dewhurst is likely to be rejected out of hand by the majority of people.
Essentially, the claim is that giant human skeletons were found in America, having evidently been buried as part of their culture.
Before reading the book, you may not accept that giant humans (let's go with eight feet tall or more) do exist. Oh, you might allow for Robert Wadlow, who was reportedly nearly nine feet tall, but not that there had been a number of humans of that height.
You should look at your own decision making process to determine what might make you accept that assertion.
The bulk of the book is reproduction of news stories.
I've read some of those stories before (I have some in my Weird Old Days Flipboard magazine, although I did not add most of them until after reading this book).
The striking thing about them is how matter of fact so many of them are...and some of the similarities.
We hear about people mistaking fossils of other types of animals as humans, but these are often described quite carefully, and reportedly examined sometimes by medical professionals.
One common thing is discoverers putting the jawbone over their own face (and it fitting easily) or seeing that the skull would fit over their own heads.
That doesn't sound like mythology or fantasizing.
If, and that evaluation will be up to you, giant humans existed in what is now the USA, and if hundreds of skeletons were found in the 19th Century, why don't we all learn about that in school?
That's where I think Dewhurst is on shakier ground.
The subtitle of the book suggests, and Dewhurst references the idea, that there was a deliberate cover up by the Smithsonian Institution.
The evidence for that seems circumstantial. An article reports that an expert from the Smithsonian is coming to a discovery site...and then the skeletons and/or artifacts aren't in the official record.
I would describe the cover up portion as an accusation of wrongdoing, and I think that requires a pretty high standard of proof. In a court of law, the prosecution might provide a motive...I'm not sure what that would be here, but I can get by without one if there was some stronger evidence: even a whistleblower would strengthen the case.
I will say that the ideas in the book are interesting...if the reports are truthful and accurate, there would certainly be a different history about the Americas than most people believe.
As to the production of the book: the one disconcerting thing for me was that the exact same words seemed to be repeated pretty often. My guess is that, in the paper book, those appear as pull quotes from the article. In my Kindle edition, though, that wasn't apparent. Dewhurst would describe what an article would say...and then the article would say it.
All of that said, I did find the book interesting. I think many people would, even if they don't believe in the truth of what is being asserted.
Be aware that religion will eventually enter into the discussion, and that some may see the suggestion that what may have been people of European descent in North America having a "superior" culture to the Native American one in the past may be offensive (to be clear, Dewhurst does not make that assertion).
Bottom line: a lot of research has gone into this book, and it will likely leave you wondering...
