I have two thoughts.
I could do something on personality theories. There is a gap in the market to look at the Myers-Briggs approach vs. the academic 'Five Factor' model vs. evolutionary psychology + the results of recent brain-imaging research. I can think of a number of powerful ideas and insights from combining these disparate schools of thought and I think the results would sell.
My other idea is reflected in the title of this piece - inspired by the famous "On Thermonuclear War". Briefly, my proposition is that any alien civilization we discover will be exceptionally aggressive and dangerous (a good self-description, don't you agree?) and that we should aim to wipe them out immediately. I will look in detail at the new hyper-telescope technologies (link) which may give us the same view of alien planets as orbital satellites give us of the earth today. I then survey methods of planetary extermination including:
- asteroid bombardment
- relativistic weapons
- flaring the star
- biological weapons
- sociological weapons.
Does this sound extreme? I think a civilization which could absorb The Simpsons is ready for my book, and I would expect it to sell by the shed load.
Joking in bad taste aside, you are invited to read the Book Proposal by clicking here.
Enjoy (expecially if you are a prospective publisher)! And actually, I think the one book could cover both of my ideas, via 'exopsychology'.
