Those who cling to the belief in blackout babies fail to accept that the same communities they point to as proof of the theory saw even greater leaps in number of births in years that weren't preceded by memorable events. Blackouts, snowstorms, and the like are more usually followed by perfectly ordinary birth rates nine months afterwards, but because human nature is what it is, we tend to remember only the events that fit the pattern we're determined to see and unconsciously discard all the rest, Thus, we'll recall that the Great Storm of 1983 was followed by a deluge of babies in the Fall of 1984, but we'll completely forget that the Great Storm of 1987 was followed by a perfectly ordinary turnout at the maternity hospitals in the Fall of 1988, or that the Great Baby Boom at the end of 1999 wasn't presaged by anything unusual that occurred in the Spring of 1999.
It is a common belief that the number of conceptions increases during natural disasters or crises that keep people confined within their homes for unexpectedly long periods of times. Nine months after such events blackouts, blizzards, earthquakes, erupting volcanoes, ice storms, and even strikes by professional football players reports about "baby booms" in local hospitals invariably appear in the media. However, these "booms" always turn out to be nothing more than natural fluctuations in the birth rate (or, in many cases, no variation in the birth rate at all). Of course, we never hear about these fluctuations when they are not preceded by some unusual event. (Conversely, when these fluctuations do occur, reporters go scrambling to find some earlier event to "blame" them on.)
