There is so much wisdom at Chocolate and Vodka (both in pro-self publishing and in surveying why the quality of self publishing will always suffer due to the Dunning-Kruger effect) that I just want you to rush over and read, and then read all the other posts around there. I spent an hour poking around and then followed the author on twitter because I want to subscribe to the newsletter!
“So, according to Dunning and Kruger, in order to combat the massive shit volcano, we would need to train every self-publisher who produces shit, and hope that they realise that they aren’t as good as they think they are and need to try a bit harder. Well, good luck with that one.
Now, it’s true that not every self-published author is on the wrong side of Dunning-Kruger. Some are on the only slightly less wrong side: Good writers whose confidence is shot because they understand that they could be better, and are over-sensitive to the gap between the quality of the work they do produce and the quality they want to achieve. Those people are better than they think they are and will publish less than they should.”
