The Modified Klein Scale for Sexual Orientation
The information contained on this page is based on a Questionnaire that was run from 2008 on this site for a while. Not all of the data has been reviewed as yet, but there is sufficient to understand that people can change through their lives.
Information on the original Klein Scale can be found by clicking here.
A summary of the modified Klein Scale responses reviewed and plotted so far can be found by clicking here in pdf format, for males from the age of 18 upwards.
Raw entries can be found in the following pdfs - these are large documents to download:
The Kinsey Scale which is the basis of the scoring can be found on the Labels page.
The modified scale is based on the assumption that people's attitudes towards their sexuality could change during their lifetime, so that they were asked to score what they thought their sexuality was at set stages of their lives (over approximately 20 year periods up to now), and what their ideal might be.
One or two comments
- There are often clear differences in the way people have scored their teens and scored their later life, as they gradually come to terms with their sexuality and decide how they are going to cope with it.
- The way in which people have scored their "ideal" situation seems to depend on how they view themselves. If they have not come to terms with their true sexuality (principally because they have insufficient experience to know), they often score as if they wanted to be "normal", whereas those who have come to terms with their sexuality, often score to match what they consider to be their true, unconstrained sexuality.
- Things like lifestyle and social preferences tend to match the way people want to live, often in an opposite gender or balanced environment, whereas sexual attraction and sexual fantasy tend to be related more to their sexual desires.
- Sexual behaviour is often influenced by a person's circumstances. Thus a homosexual person in marriage may show little or no homosexual activity (depending on opportunity) whereas they could score their sexual attractions and fantasies with a same gender bias.
- Scrutiny of responses from people who are 10 or 20 years older than you, if they have scored in a similar fashion and have a similar history, could give you a clue as to what the future might bring to you, although remember that we are all different.
I am grateful for the help and support of Anthony Venn-Brown - Author - Life Coach - Speaker who introduced me to the Klein Sexual Orientation Grid (invented by Fritz Klein) and to his various colleagues who helped me through a short piloting of the questionnaire.
