Of course it's a question of bias. You have your biases, I have mine, everyone has their own. These are always at play. And forums and other communities form around them. And if you never ask yourself what biases each place has then it's not good. That's how filter bubbles form and we lose accurateness in general.I don't think it's a question of bias on here. For one thing not enough have voted on the poll on here for there to be enough data. What you call bias, I would call business sense.
Saying that, I will echo what others have said about Reedsy and what they say it costs to publish a book in 2021. Where does their data come from, service providers or authors? I suspect the former.
Obviously people who supply services hope that the figures they quote will be more of an accurate reflection of what authors spend. No doubt there are enough authors around to keep everyone in the services industry happy, but I doubt it is accurate. I'd bet that those prices quoted by Reedsy are more of a wish list of prices that author's would hope they could afford to get their book to be the best it could be. Every credit to those who can afford the higher prices that Reedsy quote. .
If Reedsy are correct that MOST authors spend those sums, then there would be a lot of authors crying at their bank statements. Every credit to those who have those recourses, but I would suggest that it doesn't make business sense for MOST in relation to return on investment.
Reedsy: Cost of publishing a book in 2021
"Most authors spend $2,000-$4,000 to self-publish their books — this includes editing, cover design, formatting, and marketing services."
As example, some people who have cheapness bias like to call it ''business sense''. While business sense includes spending wisely, being cheap is never the full extent of it. It's more sensible to hire a professional rather than think you can do everything. But cheapskates think the difference between someone who just picked up a software tool to DIY (like Photoshop) is negligible to what an expensive or even median service provider can do. Should a vote of that kind of attitude really count? I'd say no, but it does in a poll like this. Thus the danger of polls and not knowing where bias comes from.
I agree Reedsy had prices a bit high but they have tens of thousands of authors reading their huge blog so their voting was authors not vendors (vendors voting wouldn't be a legitimate poll). The article you quoted IS NOT the poll I meant tho, I think they had a different one few years earlier.
And it doesn't mean Reedsy are right 100% anyway. It just means they might represent the different end of spectrum and they have bias for average or above quality. The truth tho, is in any place of the spectrum. Not either particular end of it. We are in an industry were you can stumble into cheap and very good still.
