One of the best-known ideas I came-up-with was also one of the shallowest: Psychological Neoteny.
This is the idea that in modern societies immature psychological attributes are retained into adulthood.
Psychological neoteny generated a lot of mass media interest in the UK, and ended-up featured as one of the big ideas of the year in the New York Times Magazine
The idea came from an editorial I wrote for the journal I edited: Medical Hypotheses:
You will see that - back in 2006 - I approved the trend of psychological neoteny - because I was pro-modernization, and psychological neoteny was an adaptation to the modern condition: a retention of the flexibility, adaptability and curiosity of adolescence into adulthood, leading to an economically and socially useful type of person.
I find it strange that the PN idea somehow found its way into the media. Psychological neoteny now has 8000 'hits' on Google, and somebody put it into Wikipedia - where (amazingly!) it stayed.
Yet I wrote the original article in a couple of hours and mostly as a semi-amusing curiosity - triggered by having noticed several photographs of various (adult) scientists who looked extremely boyish.
Anyway, as the year turned from 2006 towards 2007, I thought a bit harder about this idea that I had so casually thrown-off.
I discussed it a little with my e-mail pen-friend, the late Martin Trow (world expert on the sociology of higher education and a Professor at Berkeley) - who was about 80 years old at the time and full of the wisdom of experience. He made a few remarks about the experience of higher education delaying the psychological maturation process - perhaps even stopping it permanently; contrasting this with what happened early in his life (serving in the armed forces, training as an engineer etc).
I began reading around to look for a good proxy measure of psychological neoteny, and found age of marriage and age of first child (and total number of children) - which led to a follow-up editorial that shows signs of my becoming aware of the dark side of psychological neoteny, and therefore modernity itself.
My conclusion was: "At present it is unclear whether the trend for retaining youthful
attitudes and behaviours is overall beneficial or harmful. There are
probably social advantages from a population retaining the cognitive
flexibility to cope with (or indeed enjoy) rapid change of jobs,
locations and friends; and there are economic benefits from delayed
parenthood in women. But there will also be social disadvantages from
delayed maturity of adults, perhaps impairing social integration among
men, and reducing population fertility levels. And, at the individual
and personal level, the costs and benefits of PN may be different for
men and women, and for people with different priorities."
But this started me thinking on the subject of marriage and families, and that the current trend was obviously unsustainable - and amounted to deliberate genetic suicide.
And about who was 'bucking the trend' for later and later marriage, later starting of families, and ever smaller families.
And this led (via, I think, the work of some 'quant bloggers' such as The Inductivist and Audacious Epigone) to Rodney Stark's research on Mormons.
In US Mormons I found the exception to the marriage and fertility trends - but in a community that was very 'modern' in terms of many indices such as education, social class, salary, and the occupation of high status positions.
I became very interested in the matter of fertility - and later did some small scale studies of Mormon fertility in Britain:
In order to understand Mormon exceptionalism with respect to fertility, I read a lot about Mormonism. I enjoyed what I read, so I kept going. And I read Rodney Stark's book Discovering God.
I was already pretty expert on 'comparative religions' but from the perspective of New Age spirituality - and had supervised a PhD on the psychology of religiosity, which was (much later) published:
And of course I was already reading CS Lewis and JRR Tolkien...
So, all of these came together in some way and I became a theist, and then a Christian; and/ but a Christian who from the beginning regarded Mormonism as an exemplary Christian denomination of modernity; because (missing-out lots of other factors, including some very important people) it was my interest in Psychological Neoteny which led to an interest in marriage and fertility, which led to Mormonism, which led to Stark, which led to theism, which led to my conversion to Christianity.
