But then, I've never had difficulty lying when it was convenient, so I'm probably not the best to ask.
While I have not raised kids, I do not see why that should factor into the discussion. Your comment suggests that you are operating under the assumption that experience is the only thing that confers ability. However, you may have noticed at some point in your life that we are quite good at obtaining knowledge via the traditional means of learning from the archived experience of others. Arguably even better than learning by first hand experience, though that is up for debate. I have studied various aspects of (adult and child) psychology and sociology to satisfy my urge to understand humanity, and my thoughts on the matter are based on that gained knowledge.
While I agree that experience can lead to new insights, and can result in a more optimal utilization of your own knowledge, it is certainly not required to actually discuss a matter. Maybe the lack of practical experience would be more notable if I were trying to suggest some sort of novel ideas, but I am just stating something which has been seen time and again throughout the ages; what skills are necessary to be successful, and how to impart them to your offspring.
As you may imagine, I have spent some time trying to understand why some people raise their kids to be successful, and why others fail horribly at the act. It does not take spending 20 years to see a pattern of success or failure emerging with the application of certain techniques. So to more directly answer your question, my opinions based neither of my own experience, nor on my understanding of how kids "should" be raised. Instead, my views are based on the mass of information I have seen and read on the topic, and the trends that clearly exhibit themselves in that data.
Going further, I actually find that relying on any long term experience can at times make the results somewhat suspect. While experiencing something several times can help you understand it all the better, once you spent a better part of two decades practicing something you will almost certainly be convinced that you are doing everything correctly. To admit otherwise would be to admit your own failings which few people are willing to do, especially in an area as sensitive as child rearing. This leads to the surprisingly common situation wherein an "authority" who is trusted to make the right decisions acts contrary to the accepted scientific norms of the time. Take for example a grandmother that raised 8 children, and will expound for hours on the necessity of beatings to raising healthy and successful kids. I am sure most of the HN readers can think of a lot of other examples of this in a myriad of fields.
Obviously though, neither you, nor anyone else should make fundamental decisions regarding how to raise your child based on something some guy on the Internet said. A responsible parent should spent at least as much time as I have reading the material relevant to the topic in order to make informed decisions. What more, if it appears to a somewhat informed person that you have not done this basic work, they should, as I have with the GGP, point out the flaws in your reasoning without having to wade through comments disqualifying their opinion simply because they have not actually put what they have read into practice. If you have issues with what I said, then by all means please present them, and the supporting arguments, for me to discuss or concede as necessary, but do not for a second think that you can discount me from the discussion simply because I do not adhere to the strict experience requirements that you feel are necessary before even think about the topic.
