What's an 'honest person position'? Mercury in Sagittarius is honest about what they think at the time for example, but it doesn't make them honest.
Honesty wielded properly is more of a skill than a totally innate quality. People lie constantly, to themselves, to others, and to their subconscious. Sometimes deceptions are necessary. Others are so blunt that they go around pissing off everyone.
Most Astrologers are too young, do not have enough social experience, can't blend meanings and hence don't look at the Chart correctly.
In the Middle Ages, rightly or wrongly, analyzing a human being's Birth Chart was considered the most difficult and intricate form of ALL Astrological undertakings. Finding objects, asking questions or predicting the result of a situation, studying the Charts of national catastrophes, weather for farmers, illness related Astrology, eclipses, these were all taught to initiates first, long before moving on to Natal Charts. A human being is always complicated.
Also, WoadWarrior is correct. People mature at different rates. In my estimation, parts of the chart are really not activated until age 30-40, or maybe a lot later than this. If you're some kid in school you haven't experienced a lot of what the Chart even talks about. Maybe in the Industrial Revolution and being forced to work these would be 'wrung out' earlier, but most people don't experience that.
