I took sharpiemom's post as sarcasm and had a good laugh. After all, she was "sitting on the recliner just waiting for the symptoms to kick in!"

Scientific study is to be undertaken by disinterested parties. The source of the money to do the research may be a giant red flag to you, but it is a much smaller concern to those who understand the process. This is entirely different than if the researchers were employed by the industry or owned stock in the industry. Such was not the case. Do you really think there is a giant conspiracy by scientists to kill you with cell phones?

http://www.radiationresearch.org/pdfs/15reasons.asp
Website with a non industry current August 2009 study!
"The exposé discusses research on cellphones and brain tumors and concludes:
Once again, you have absolutely failed to present credible evidence.

Nor did you paste up a study. You pasted a website that hosts an "expose" critical of a WHO study.

But let's look at why your "expose" isn't credible.

1. It has NOT been published in a scholarly journal, just on a politically motivated website.. nor has it been peer reviewed.

2. It contains no original research nor any statistical analysis.

3. Did you notice any of the study authors stating their education? Do any of them have an MD? PhD? MS? Anything? Shady business...

4. Credible articles have acknowledgments followed by content in academic format. Your "exposé" has a title page that looks like it was made for a high school English Class followed by a page of larger than life quotes by a politician followed by a two page list of endorsements including links to pseudoscience websites like this: http://electromagnetichealth.org/

5. Therefor, the "exposé" was written and edited by those with a DIRECT financial interests at stake. (This is a far more inappropriate than a financial interest merely funding research. Academics are supposed to be independent.) All of these people run organizations pushing the cellphone cancer agenda.

6. Briefly glancing through the "exposé," they are long on suggestion and accusation and short on facts. That makes your link about as reputable as this debate... no... less. Take one example amongst many: the section where they imply that cell phones cause cancer by quoting a study that showed cancer rates in children who had been exposed to X-rays. They clearly don't understand the difference between ionizing and non-ionizing radiation. Since you've surely learned in this thread the difference between ionizing and non-ionizing radiation through the course of this thread, I'll just assume you posted this exposé containing such pseudoscience because you read it as thoroughly as the Swedish Study that you claimed said the opposite of what it actually did. Did you read the study your expose is criticizing?

7. As with everything else you've posted, YOUTUBE!!!!!!! That alarmist video I turned off when the lady narrating stated that correlation implied causality. That caused her to lose all credibility.

Gavel Correlation != Causation
Remember your statistics class that you had to take to become a RN?




You must avoid the logical fallacy of correlation = causation:

Here are some examples:

Reverse Causation Failure:
Correlation: The worse the patient, the more nurses come to the trauma bay.
Causation: Therefor nurses make the patient worse.

Lurking variable example:
If the grass turn green when it is humid, the grass didn't make it humid. The rain caused both.

Falling asleep with your shoes on may correlated with a headache.
Crackpot: Shoes cause headaches!
Scientist: Passing out from the alcohol caused both.
True Crackpot: I'm burning my shoes as a precaution!

Coincidence

Crackpot: The lack of pirates is causing global warming!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Scientist: Well, what are you waiting for? Go to Somalia and become a pirate already!
Crackpot: I will! Pirates don't have to worry about cellphone radiation either!

Applied to Cell phones

Correlation: "Cancer diagnosis are up! Cell phone usage is up too!"

Crackpot Claim: "Therefore Cell phones cause cancer!!!!!!!!!!!!!!!!!!!!" <-This is not supported by the correlation. Statistical analysis is required for that... something your expose didn't have ANY of.

Real Scientists Outlook: "Well, what else could explain cancer diagnoses being up? Let's make a list then try to run some statistical analysis to see which it is, if any (or many)"

So the scientist asks:
"If we wish to assume the higher cancer Cancer in a large population have a related etiology, then the carcinogenic agent should be widespread... perhaps environmental:"

"Is it a chemical in the water? air? food supply? consumer product like sunscreen?"
"Is there something that has been removed from our environment that used to protect us?
"Is it due to the widespread increase in pharmaceuticals?"
"Is it due to low level non-ionizing radiation?"
"Are the cancer numbers really up or are we just getting better at diagnosing them due to higher screening rates and better diagnostic tools?"
"Are the cancer numbers higher because people are not dying of other diseases that would normally kill them before the cancer kicked in?"

Some of those possibilities are entirely likely and others are very unlikely. "Is it due to increased exposure to low level non-ionizing radiation?" is just one possible correlation that could be found to have causal relationship (it hasn't). An honest scientist has to ask those questions and then groups test each hypothesis.

AND WHEN THE TESTS FAIL TO SHOW A CAUSAL RELATIONSHIP?

When someone has an emotional attachment to a hypothesis and won't let it go even when the shows that there is NOT a causal relationship and nobody has come up with an underlying theory to support the idea, nothing but correlation, holding the hypothesis true is delusional thinking, not scientific thinking. Believing that there is a massive conspiracy to hide that truth and only a select few can see past the smoke is the hallmark of the uneducated trying to feel like they have a leg up on the rest of the world.

If you read the websites of the people pushing the "cellphone cancer" agenda, you quickly find that they think it's not just cellphones. It other unrelated radiation types: cordless phones, power lines, wifi, radio stations, etc etc etc. Then you'll find that it's not just cancer that they think it causes: Alzheimers, parkinsons, autism, CFS, schitzophrenia, depression, deafness, ADD, insomnia, headaches, eye aches, tooth aches... EVERYTHING. What is their basis for these thoughts?

It is an extension of the "correlation implies causation" illogic.

"More cancer and more cellphones, therefor cell phones cause cancer... therefor cell phones are bad! Therefor other bad things that happen are caused by cell phones! Therefor cellphones cause my migraines... and my insomnia... and my dog's smelly smelly farts!"

Don't fall for that kind of stupidity.

Thank you for the chuckle!
I have always loved cockeyed logic. I simply have to send this entire thread of a friend of ours.
He teaches math, logic and stats, and he'd appreciate the entire thread and especially this last post I've quoted.

Just have to weigh in here to say that consensus is NOT science.

And SummitAP . .. where have you been all my life?

I think statistics and research methods both need to be required courses in elementary school. Seriously.

Thank you!

Lightbulb Ionizing vs Non-ionizing
I wrote this up just to be concise for anyone still unclear on the topic.

When radiation is absorbed it can cause two possible reactions:

1. Ionization Radiation and Types of Interaction:
When ionizing radiation interacts with matter, it breaks a chemical bond or creates a free radical by directly knocking free an electron. You need a LOT of energy to do this directly in most materials.

1a: In some materials in certain states you need photons with as little as a couple of hundred electron volts (e.g. UV-A) to cause Photoelectric Effect ionization, e.g. hydroxyl group ions (free radicals) production in human cells. You need radiation with more energy (higher frequency) than visible light.

1b: In most materials most of the time, you need several 1000 electron volts (X-ray/gamma) to cause ionization via the Compton Effect. Sometimes these can cause "chain reactions" of multiple ionizations, such as soft X-ray bombardment of Aluminum (or especially when dealing with particle radiation, but that's another topic).

Ionizing Radiation Effects on Living Cells

Ionizing radiation breaks chemical bonds within molecules that do important jobs in a cell, destroying the cellular machinery and causing aptosis (programmed cell death) or damaging DNA causing cell death, mutation, perhaps a cancerous reproduction mutation. Generally, to get that type of mutation, a lot of other ionization damage also occurred in the cell so often the cell is killed anyway.

Ionizing Radiation Effects on Humans

Cells that reproduce most often have the least time to repair and are therefor the most sensitive to radiation damage: the lining of your intestines replace itself every 3-5 days. New RBCs and leukocytes are constantly forming in your bone marrow. That is why we see WBC countl changes and GI problems as the first signs of ionized radiation exposure (and the ONLY acute signs in lower doses where any sign at all is created) and why radiation therapy patients are more prone to infection.

2. Non-ionizing Radiation

When radiation doesn't have the energy to knock off electrons and break bonds, it is known as non-ionizing. THIS ENCOMPASSES ALL RADIATION FROM:
VISIBLE LIGHT (200-300 electron volts)
INFRARED (200 eV down to 0.001 eV)
MICROWAVE RADIO (0.001eV to 0.000001eV) and weaker. Cell phones again are putting out about 0.0000035 eV photons (versus say a 50,000 eV photon from an X-ray machine).

Non-ionizing interactions

When these low energy non-ionizing radiation interacts with matter, they cause molecules to vibrate, to gain speed. To speak properly, HEAT IS TRANSFERRED TO THE AFFECTED MOLECULE. What happens next depends on how much heat you apply:

Non-Ionizing Radiation Effects on Living Cells

2A Critical Heating: If you apply a LOT of low energy radiation, you can raise the temperature high enough to deform complex molecular structures (like quaternary structure of proteins at ~120F) or even high enough to cause state changes (melting/boiling) or chemical reactions (fire!). You are heating the substances.

2B Minor Heating: If you apply anything less than enough energy to do what is mentioned in 2A, nothing happens to the chemical structures. It gets warmer. Heat is conducted away to surrounding materials.

Non-Ionizing Radiation Effects on Humans

2A applied: If you stand in front of a 10,000 watt directional microwave repeater antenna, you will receive enough thermal energy to denature your proteins at about 120F, which causes burns. If you don't move fast, it could boil water in your cells! It's like standing in a microwave oven!

2B applied: If you stand next to a cellphone, only a TINY amount of heat energy is delivered by RF... a negligible amount. Because of your bodies thermoregulation abilities, the worst cellphone would be able to theoretically raise local tissue temperatures by a fraction of a degree. The heat just conducts away through your tissues and blood. Repeated low level heating is no more worrysome than taking hot showers every day.
