This couldn’t be more incorrect. In Smith’s day your sources of information would be interpersonal, or one of your local newspapers. Newspapers in the 18th century wore their bias on their sleeves and had very particular world views, they were anything but neutral. You might also learn about commercial interests in coffee houses where stock markets first developed. This was a place where people were trying to sell you something, like shares in a commercial shipping business.

I’m always astonished that people make these claims about Smith’s work without having read his books or any relevant history.
