Psychologists have discovered that people performed better in memory tests when
the weather was bad and they were feeling grumpy.
The research discovered that the worse the weather and the more depressed the
individual, the sharper their brain.
The findings were made by the University of New South Wales School of
Psychology. The team carried out the study by questioning shoppers at a Sydney
store over two months.
They tested their memory and found that they recalled three times as much
information when the weather was bad and they were feeling down.
Professor Joe Forgas, who led the research, said: "It seems counter-intuitive
but a little bit of sadness is a good thing.
"People performed much better on our memory test when the weather was unpleasant
and they were in a slightly negative mood.
"On bright sunny days, when they were more likely to be happy and carefree, they
flunked it."
The research mirrors previous research that showed that gloomy students received
better grades than those that were happy.
"They point to a growing body of evidence that the way people think, the quality
of their judgements and the accuracy of their memory are all significantly
influenced by positive and negative moods," the researchers said.
They concluded that "memory is far more accurate" on gloomy days.
Professor Forgas added: "More and more evidence from experiments like this is
showing that mild, fleeting moods can have a profound yet subconscious influence
on how people think and deal with information.
"Being happy tends to promote a thinking style that is less focused on our
surroundings. In a positive mood we are more likely to make more snap judgments
about people we meet. We are more forgetful and yet we are paradoxically far
more likely to be overconfident that our recall is correct.
"Mild negative mood, in turn, tends to increase attention to our surroundings
and produce a more careful, thorough thinking style.
"Accurately remembering mundane, everyday scenes is a difficult and demanding
task, yet such memories can be of crucial importance in everyday life, as well
as in forensic and legal practice.

We studied 121 African populations, 4
African American populations, and 60 non-African populations for
patterns of variation at 1327 nuclear microsatellite and
insertion/deletion markers. We identified 14 ancestral population
clusters in Africa that correlate with self-described ethnicity and
shared cultural and/or linguistic properties. We observe high levels
of mixed ancestry in most populations, reflecting historic migration
events across the continent. Our data also provide evidence for shared
ancestry among geographically diverse hunter-gatherer populations
(Khoesan-speakers and Pygmies). The ancestry of African Americans is
predominantly from Niger-Kordofanian (~71%), European (~13%), and
other African (~8%) populations, although admixture levels varied
considerably among individuals. This study helps tease apart the
complex evolutionary history of Africans and African Americans, aiding
both anthropological and genetic epidemiologic studies.
3. NonNon-Paternity Events

Some interesting articles and surprising information
Statistics maybe of questionable reliability: Sometimes they are based on
extrapolations from inherited medical conditions
where the underlying assumptions are incorrect. Other sources are inferences
from paternity tests but only men with
a motivation to take tests are liable to do so.
Statistical Normalcy is that of a society with family values, economic and
social stability, and relative egalitarianism.
In such cases the figure will be from 1.3 to 2 %. Examples of such groupings
include Orthodox Jews,
Mormons, similar religious groups, the citizens of Switzerland.
In promiscuous societies it reaches up to 30% but seems to taper off after that.
Quotations below are presented for the sake of interest.
They are not necessarily to be presumed reliable.
NPEs
Statistics:
Canada 10%
"that as many as 30 percent of American, British and Italian babies are secretly
illegitimate"
the rate of "false paternity" in the U.S. is estimated to be between two and
five percent
An evolutionary biologist at the University of Manchester estimates that in 10
percent of British births, the mother was sleeping with a man who had "stronger"
sperm than her husband.

10.1% from Schact and Gershowitz in a study of correlation between blood groups
and fatal pediatric diseases for negroes.
"Men with high paternity confidence (subjects in genetic studies) have very low
rates of nonpaternity (median = 1.9%, N = 22).
Men with extremely low paternity confidence (cases of disputed paternity
resulting in paternity tests) have much higher levels of nonpaternity (median =
30.2%, N = 30).
When the high and unknown paternity confidence samples are combined, the median
nonpaternity is 3.9% (range: 0.4 ? 32.0)."
"On the whole, the evidence suggests relatively low rates of misattributed
paternity, at least in Western countries - perhaps between 1% and 3%". (This
statement appears to be based on "inspection" rather than "statistics").
England (Liverpool): ... Blood group studies indicate levels of paternal
discrepancy .... up to 20-30% ....
"Actual figures range from 1 percent in high-status areas of the United States
and Switzerland, to 5 to 6 percent for moderate-status males in the United
States and Great Britain, to 10 to 30 percent for lower-status males in the
United States, Great Britain and France. Moreover, the men most likely to
sexually hoodwink the lower-status males are men of higher status."
Sephardic Kohanim (Jewish priests): 0.4%.
Ashkenazic Kohanim (Jewish priests): 1.2%
"These low estimates of around one to three per cent from UK laboratories
carrying out pre-natal diagnosis for cystic fibrosis are probably the most
accurate estimates":
"And it turns out that misattributed paternity is as minimal as 1% among very
high-status American males but up to 30% among unemployed, deprived, inner-city
males."
"In Utah, or at least in the families at the heart of the various genetics
studies over the years, the rate of "nonpaternity," as it is called, is less
than 1 percent, private industry researchers and University of Utah scientists
say. "They stick to their knitting," said Mark Skolnick, the chief scientist at
Myriad Genetic Inc."
