" In the statistical gargon used in psychology, p refers to the probability that the difference you see between two groups (of introverts and extroverts, say, or males and females) could have occurred by chance. As a general rule, psychologists report a difference between two groups as 'significant' if the probability that it could have occurred by chance is 1 in 20, or less. The possibility of getting significant results by chance is a problem in any area of research, but it's particularly acute for sex differences research. Supppose, for example, you're a neuroscientist interested in what parts of the brain are involved in mind reading. You get fifteen participants into a scanner and ask them to guess the emotion of people in photographs. Since you have both males and females in your group, you rin a quick check to ensure that the two groups' brains respond in the same way. They do. What do you do next? Most likely, you publish your results without mentioning gender at all in your report (except to note the number of male and female participants). What you don't do is publish your findings with the title " No Sex Differences in Neural Circuitry Involved in Understanding Others' Minds." This is perfectly reasonable. After all, you weren't looking for gender difference and there were only small numbers of each sex in your study. But remember that even if males and females, overall, respond the same way on a task, five percent of studies investigating this question will throw up a " significant" difference between the sexes by chance. As Hines has explained, sex is " easily assessed, routinely evaluated, and not always reported. Because it is more interesting to find a difference than to find no difference, the 19 failures to observe a difference between men and women go unreported, whereas the 1 in 20 finding of a difference is likely to be published." This contributes to the so-called file-drawer phenomenon, whereby studies that do find sex differences get published, but those that don't languish unpublished and unseen in a researcher's file drawer.

" I cannot, of course, prove that there is no supervising deity who invigilates my every moment
and who will pursue me even after I am dead. (I can only be happy that there is no evidence for
such a ghastly idea, which would resemble a celestial North Korea in which liberty was not just
impossible but inconceivable.) But nor has any theologian ever demonstrated the contrary. This
would perhaps make the believer and the doubter equal—except that the believer claims to know,
not just that God exists, but that his most detailed wishes are not merely knowable but actually
known. Since religion drew its first breath when the species lived in utter ignorance and
considerable fear, I hope I may be forgiven for declining to believe that another human being can
tell me what to do, in the most intimate details of my life and mind, and to further dictate these
terms as if acting as proxy for a supernatural entity. This tyrannical idea is very much older than

Christianity, of course, but I do sometimes think that Christians have less excuse for believing, let
alone wishing, that such a horrible thing could be true. "

" About 4,400 years ago 8 people stepped off Noah’s ark. According to the United Nations Population Growth Statistics, the world’s population grows at about .47% per year. That is the growth rate for all civilizations who kept records. Suppose you put $8.00 in the bank 4,400 years ago and received .47% a year. How much money would you have? What a coincidence! It would be about $7,000,000,000. That’s kind of odd, because 4,400 years ago 8 people stepped off the ark and now we have about 7,000,000,000 people on planet earth. God’s math works! Compound interest is something we teach to seventh-graders. You don’t have to be a professor to figure this out. A twelve-year-old can do the calculation. Ask any seventh-grader, the algebraic equation looks like this: A=P (1+r/n)t . . . where " A " is the ending amount (about 7,000,000,000 in this case), " P " is the beginning amount (8 in this case), " r " is the interest rate (.47% in this case), " n " is the number of compoundings a year (1 in this case), and " t " is the total number of years (4,400 in this case).pg 11 "

" He imagined a town called A. Around the communal fire they’re shaping arrowheads and carving tributes o the god of the hunt. One day some guys with spears come over the ridge, perform all kinds of meanness, take over, and the new guys rename the town B. Whereupon they hang around the communal fire sharpening arrowheads and carving tributes to the god of the hunt. Some climatic tragedy occurs — not carving the correct tributary figurines probably — and the people of B move farther south, where word is there’s good fishing, at least according to those who wander to B just before being cooked for dinner. Another tribe of unlucky souls stops for the night in the emptied village, looks around at the natural defenses provided by the landscape, and decides to stay awhile. It’s a while lot better than their last digs — what with the lack of roving tigers and such — plus it comes with all the original fixtures. they call the place C, after their elder, who has learned that pretending to talk to spirits is a fun gag that gets you stuff. Time passes. More invasions, more recaptures, D, E, F, and G. H stands as it is for a while. That ridge provides some protection from the spring floods, and if you keep a sentry up there you can see the enemy coming for miles. Who wouldn’t want to park themselves in that real estate? The citizens of H leave behind cool totems eventually toppled by the people of I, whose lack of aesthetic sense if made up for by military acumen. J, K, L, adventures in thatched roofing, some guys with funny religions from the eastern plains, long-haired freaks from colder climes, the town is burned to the ground and rebuilt by still more fugitives. This is the march of history. And conquest and false hope. M falls to plague, N to natural disaster — same climatic tragedy as before, apparently it’s cyclical. Mineral wealth makes it happen for the O people, and the P people are renowned for their basket weaving. No one ever — ever — mentions Q. The dictator names the city after himself; his name starts with the letter R. When the socialists come to power they spend a lot of time painting over his face, which is everywhere. They don’t last. Nobody lasts because there’s always somebody else. They all thought they owned it because they named it and that was their undoing. They should have kept the place nameless. They should have been glad for their good fortune, and left it at that. X, Y, Z. "
