That is a lot of exploration and investigation already. But, being the curious sort, I feel one really good question usually inspires two or three dozen more. And so I have prepared for you a list of additional questions (and some preliminary answers). It's my hope that this Q&A monologue will engage readers and inspire something more like a dialog. If you share my interest in this topic and would like to advance the conversation, please feel free to chime in--via comments.
Here we go!
- Does it matter if you measure the ratio on your left hand or your right hand? If the measurements are different, which one is more accurate?
- If your instincts are hardwired, how much choice do you really have in the heat of the moment? Are people with low 2D:4D ratios more likely to be aggressive drivers?
- Is there a correlation between finger length ratio and other measures of personality, such as the MBTI profile? Are certain ratios disproportionately represented among Es or Is, for example?
- Is there a correlation between finger length ratio and a person's sex (male, female, or intersex), sexual orientation (i.e., gender identity, e.g., male, female, trans, queer), or sexual preference (asexual, heterosexual, bisexual, homosexual)?
- What are the ranges of ratios that have been measured?
- Are there any published studies correlating the effects of pre-natal androgens? For example, to what degree are finger length ratios and facial symmetry correlated?
- To what extent should finger length ratio influence your choice of a potential mate? Should the ratio matter more or less than, say, a zodiac sign? In other words, is the finger length ratio merely a persistent but meaningless bit of pop psychology, or is it a window into serious insight?
- What, if anything, do these topics have in common? How are they related if at all?
- Astrology (signs of the zodiac)
- Parapsychology (hypnosis, extra-sensory perception, telepathy, etc.)
- Phrenology (reading the bumps on a person's skull for insights into brain structure and function)
- Chiromancy (reading the proportions of a persons hands and fingers for predictions of future health and well-being)
- Finger Length Ratio
- Positive Psychology
- Myers-Briggs Type Indicator
- Abnormal Psychology
