Painea dauneaza grav sanatatii stiintifice

Iata un exemplu stralucit despre cum statistica ajuta progresului stiintei. Iata un exemplu de cauzalitate de manual, de predat la clasa, la studenti, si la cursul de logica, si la cel de metodologie, si la cel de statistica, si la cel de meteorologie.

Iata o inferenta bine stapanita. Iata de ce nu se poate analiza corelatia dintre comportamentul de vot si variabila dihotomica viu - mort. Pentru ca toti cei care voteaza sunt in viata (stiu, stiu: o sa spuneti ca listele electorale sunt pline de esceptzii, cu sc, in cazul in care nu v-atz prins de grafia voit sc-izata).

Iata cum A ==> B atunci cand A = 1.

:) :p


1. More than 98 percent of convicted felons are bread users.
2. Fully HALF of all children who grow up in bread-consuming households score below average on standardized tests.
3. In the 18th century, when virtually all bread was baked in the home, the average life expectancy was less than 50 years; infant mortality rates were unacceptably high; many women died in childbirth; and diseases such as typhoid, yellow fever, and influenza ravaged whole nations
4. More than 90 percent of violent crimes are committed within 24 hours of eating bread.
5. Bread is made from a substance called "dough." It has been proven that as little as one pound of dough can be used to suffocate a mouse. The average North American eats more bread than that in one month!
6. Primitive tribal societies that have no bread exhibit a low incidence of cancer, Alzheimer's, Parkinson's disease, and osteoporosis.
7. Bread has been proven to be addictive. Subjects deprived of bread and given only water to eat begged for bread after as little as two days.
8. Bread is often a "gateway" food item, leading the user to "harder" items such as butter, jelly, peanut butter, and even cold cuts.
9. Bread has been proven to absorb water. Since the human body is more than 90 percent water, it follows that eating bread could lead to your body being taken over by this absorptive food product, turning you into a soggy, gooey bread-pudding person.
10. Newborn babies can choke on bread.
11. Bread is baked at temperatures as high as 240 degrees Celsius! That kind of heat can kill an adult in less than one minute.
12. Most bread eaters are utterly unable to distinguish between significant scientific fact and meaningless statistical babbling.

In light of these frightening statistics, we propose the following bread restrictions:

1. No sale of bread to minors
2. A nationwide "Just Say No To Toast" campaign, complete celebrity TV spots and bumper stickers.
3. A 300 percent federal tax on all bread to pay for all the societal ills we might associate with bread.
4. No animal or human images, nor any primary colors (which may appeal to children) may be used to promote bread usage.
5. The establishment of "Bread-free" zones around schools.

Ce de corelatii domnu sociolog. :-)

Camil Stoenescu spunea...

bun, bun așa. oricât am repeta până la obstinație „corelația nu înseamnă cauzalitate”, se găsesc minți crețe care să nu fie de acord. tot așa am găsit pe Internet corelația dintre numărul piraților și încălzirea globală :))

Dar de cozonac? Nimic?
Pe mine ala ma interesa.
Daca poporul s-a tampit de la paine, sa manance cozonac.
Multa lume nebuna...

Sau lucrarea de diploma a lui Bula: "Influentza paralelismului de cale ferata asupra ciclului menstrual la ratzele salbatice"
