Many of Graham Hancock’s views seem to raise a lot of anger in his field, and that seems to be because people have forgotten the value in the saying “strong opinions loosely held”. I think the idea of having a strong opinion, but being open to changing it is a challenging, but valuable skill set that can translate to just about anything.
You should constantly be searching for newer and better data to then update your beliefs accordingly. This is a hard thing to do, admit that you could be wrong. Especially now with the internet and social media recording our thoughts over the years. This seems to make the situation worse, as people have years of articles, tweets, podcasts, etc. saying one thing – there is a lot of momentum to keep pushing that idea. Being presented with data that contradicts that viewpoint typically leads to digging in even deeper.
I gave this book 4/5 stars – I thought it was really interesting, and the audio book was entertaining to listen to, but I do not think this book is a “must read” for everyone. I really like to entertain the idea of a lost civilization, and the question Graham raises of the mounting coincidences is one worth looking into.
