I'm not playing Mr. Citation. If you re-read my comment I explicitly say that there is some great information here. When people simply give advice based on their history - things like "use your money to live closer to work" is good advice. You don't need a citation for this; it's just someone's advice and it's good advice. "Perhaps you haven't considered the great benefits from using your money to cut down your commute time; you may reflect how negative the daily commute is" is an excellent suggestion. However the specific advice I quoted, e.g. "Buy a more expensive bed", "eat 'good' food", is useless, potentially harmful advice without citation. Already there are responses to my parent comment about how they found an in-expensive bed is actually preferrable. It would be infinitely more useful if someone actually discussed recent research in to different beds as advice. Anecdotal recommendations in this area are useless and ironically they propagate the same folklore of 'common wisdom' that this quora question specifically mentioned in the title: "advice... against common sense or wisdom".
