A Conversation About Critical Thinking

Fear, Reason, , , , , , , , , ,

Why is Critical Thinking important?

Arguably, we live in a time when it has become increasingly important to carefully parse data, even, as it turns out, in casual conversation and friendly communication. The rampant spread of misinformation in the Age of Social Media is nothing new. Conspiracy Theorists and intentional hoaxsters have been an ever-more-apparent online presence since the rise of newsgroups. Even in those near-forgotten days of Lost History prior to our every moment getting logged for “posterity” in the cloud, we had plenty of access to active (and more easily identifiable) paper sources of deliberate misdirection ranging in credulity from The Weekly World News to The National Inquirer — publications finding a non-ironic insurgency in recent years as their online brethren like NaturalNews, InfoWars, and WorldNewsDaily have added to the fodder for the less-Luddite paranoid contingent.

For the sake of reason, it is essential for all of us to adhere to certain standards of Critical Thinking. Just for purposes of general, civil communication, we should all want a basic, coherent understanding of the facts of our world. Philosophical differences aside, it should be a simple task to understand the foundations of science and recognize pseudo-scientific rhetoric as what it is; it should be easy enough to discount rigorously anti-intellectual arguments and logical fallacies

Lately, I have written a few posts on critical thinking and promised an interview on the topic. Although I recorded this some weeks back, I have finally delivered on the promise to upload it.

Logical Fallacies, the Enemy of Critical Thought

Following are a few fun pages that list logical fallacies. They present them differently, so it is worth visiting a few of the sites to get a feel for how they lay them out or categorize them, but generally speaking, they cover a lot of the same ground. Enjoy the journey!

Chemo and I Had a Pretty Good Run

Cancer, Health and Wellness, , , , , , , , , , , , , , ,

My recent post on dealing with change and adversity was inspired in no small part by a change I am facing in my own life, one rife with uncertainty and heavy with anticipation. The last CT scan I had showed that my primary tumor, the one by which we gauge progression or lack thereof, was still within the technical boundaries of business as usual. That is to say, its lateral dimensions had not changed significantly since the previous scan, and overall had not grown enough over the similar measurements from a year or two years ago to precipitate anxiety. But CT scans are, for lack of a better term, a bit fuzzy. The images are fairly clear, but the data is difficult to measure with absolute precision.

My first CT scan machine from October 12, 2014, and still one of the more peaceful places I know. I have taken about a dozen rides through that hole by now.

Because CT scans are essentially three-dimensional, but are viewed on two-dimensional screens, comparisons between scans are inherently imprecise. The angle of a subject’s body, how inflated the lungs were, the position of the subject within the imagining chamber, all figure into subtle differences between the final scans. On top of that, because the images are basically multitudes of cross-sectional snapshots, a comparison must be made by selecting the closest approximation to the “same” image between scans from different times. I’ve looked at lots of these — in fact, I keep digital copies of all my scans for reference or posterity — and I’ve used the tools to line up and measure my tumor as best I can.

And in two dimensions, at the standard viewing cross-sectional approximation, my mass looks very similar from scan to scan, every three or so months since this process began. My chemotherapy was clearly doing what it was intended to do, which was to prevent progression of the disease. Progression is generally defined in terms of the length of the tumor, but we all know that tumors are bundles of cells that grow and change along more than just one axis.

I was never under any illusion that the chemo would cure me — there is no official cure for Stage 4 Lung Cancer. Any time that the chemotherapy could afford me by maintaining stasis has been considered a luxury and at over two and a half years on this particular regimen, I have been the longest continuous success case that many on my medical team have known. So the next time I see most of them will be a special, bitter-sweet occasion.

Because the time for change has come. Continue reading Chemo and I Had a Pretty Good Run →

Beyond the Shame of Change, Adversity, and Grief

Reason, , , , , , , , ,

Nothing is forever, as the saying goes. And it seems true in terms of human experience. Change is inevitable. You can’t please all the people all the time. Time will tell. What doesn’t kill you makes you stronger. But, of course, you can’t judge a book by its cover because the grass is always greener on the other side. Also, that thing about picking your friend’s nose.

I am clearly not above the occasional inspirational bracelet.

Just not that one about everything happening for a reason. I’ll concede that there are certainly arguments for cause and effect — in fact, very much so, which is essential understanding when it comes to actually dealing with the issues that are thrust upon us in spite of our best efforts and desires. To suggest that everything happens for a reason is immensely wrongheaded and, even with the best of intentions, is ultimately unhelpful.

This does raise the issue — when suffering or change of any sort occurs — of how one is to cope if there is no purpose behind the suffering or change. Continue reading Beyond the Shame of Change, Adversity, and Grief →

Flying On Chemo and Other Fun Ideas

Jeffrey Poehlmann- My wife, who cares about me deeply, is inclined to encourage me to rest. This is especially true for the week following my chemo infusion, though any time she sees me on my feet for an extended period, carrying “too much” around or otherwise pushing my body forward with some task, I’m likely to get the suggestion to “take it easy” or, more bluntly, “go lie down.” It isn’t that I don’t understand why — especially if I’m wearing shorts. My legs have taken to swelling up like I have elephantiasis some days, though thankfully it is just water retention… READ MORE

The Meaning of Normal

Cancer, Health and Wellness, , , , , , , ,

I have been fascinated by the suggestion that life with cancer somehow equates to “a new normal” in my families existence. I don’t know what that is supposed to mean, exactly; isn’t “normal” supposed to be an objective center, a median experience, the fulcrum of an ever-swinging scale? But nowhere does the relative nature of normality present itself so clearly as with the slide into a chronic, managed illness.

Time to End the Anti-GMO Fearmongering

Business, Fear, Health and Wellness, Politics, Reason, , , , , , , , , , , , , , , ,

Here’s a thought that needs to be considered. Since the United States is not doing its part to fight global climate change, nature will not be able to keep up. This REQUIRES us to be open-minded about the advantages science offers to help our species adapt. Science-denial is one of the biggest reasons we are in this mess, but science can help mitigate the damage if it is embraced and supported in a reasonable, methodical and pro-active manner. One of the areas that must be re-evaluated by many is the use of GMO crops.

GMO vs Non-GMO corn crops.
Sometimes a little modification goes a long way.

There is overwhelming evidence from unbiased sources that show the safety of these crops, many of which are modified explicitly to be able to grow under hotter and drier conditions, or in soil that would not otherwise support proper plant development. Already, without the use of GMO crops, it would be difficult to keep up with the food production needs of the planet. Within the next decade, there is little doubt left that human food will be largely reliant upon GMO crops for minimum sustainability. I propose that it is time to look at the science objectively and stop reacting to fear-based marketing that mostly just serves alternative health websites and their advertisers or overpriced processed food manufacturers.

Critical Thinking and the Rush to Organics

Health and Wellness, Reason, , , , , , , ,
From the Forbes.com article by Steven Savage, “Why I Don’t Buy Organic, And Why You Might Not Want To Either”

In the spirit of an interview I will be conducting tomorrow on Critical Thinking, I invite you to check your confirmation bias before reading the link below. Now, more than ever, this is becoming an essential skill, especially in the age of social media and 10,000 clicks per second “information” sharing.

Also essential is the ability to differentiate legitimate viewpoints from pure nonsense. (“Nonsense” would be any argument for the existence of chemtrails, for example.) A “legitimate” viewpoint always requires two things: clear logic and reliable sources. This is an incredibly low bar, but people, it seems, are often inclined to stoop much lower.

As a disclaimer, I buy a lot of organic food. But not because I think it is safer or healthier. I am much more inclined to buy LOCAL, which has a greater positive impact than organic and often tastes better, too, though I am fortunate enough to live in an area where much of the local is organic, if that is what I am looking for. But I have also talked with people who source organic for their products about why sometimes they specifically choose non-organic, not the least reason being that it is often ethically superior and more environmentally friendly NOT to be organic. Organizations like the EWG (Environmental Working Group) tend to only tell a distorted part of the story, and they certainly present data from a heavily skewed perspective (we expect this from corporate mouthpieces for Big Agriculture, and the EWG is no different — it is just a corporate propaganda arm for the organic foods industry).

But, like I said, if you can, let go of your confirmation bias. Assume that what you “feel” isn’t necessarily true. Assume that you are wrong, or at least only partially right, and that maybe you will find something to fill in the blanks and help you arrive at a reasonable conclusion. It’s good practice. We all need it. Only an exercised skill stays sharp and critical thinking is no different.

My Story: Lung Cancer and Chemo and a Changed Life

Cancer, Health and Wellness, , , , , , , , , , ,
An in fusion needle being set in my arm.
Infusion time!

My story begins this way, elliptically, perhaps by design or perhaps because this is two days into my cycle… 48 hours ago, I was sitting in a comfortable chair at my chemo spa, settling back for a needle while a warm massage pulsed against my back. This was my 38th or 39th infusion since I began chemotherapy in December of 2014, almost exactly 2.5 years ago as I write this, on consistent three-week cycles with only one or two exceptions made for travel. As a Stage IV NSCLC patient, I suppose this makes me a “lucky” fellow because I tolerate my treatment well and seem to be holding steady through each of my scans. Life isn’t what I used to expect it to be, but that isn’t all bad. I’ve learned a few new tricks, I’ve changed my focus, I’ve accepted some limitations and tried to defy others.

In June of 2014, I was, as they say, the “picture of health.” I was working out again, moderately at least, for the first time in years; I was excited about starting a new phase in my career and had begun actively interviewing for positions that would give my life new structure and alleviate a huge amount of the stress I was under financially and emotionally. It had been a complicated few years leading up to this point and I had been paying for a few poor decisions, some unforeseen misfortune in the housing market, a few stumbling blocks in my home life, and regrets that I should never have allowed to affect me (but I had). Before this, I had a relatively successful career in film and video production, mostly in commercials but with a few independent movies under my belt and forays into other mediums, but the work itself was costing me a connection with my new daughter and domestic strain that was simply not worth exacerbating. So I decided to phase that work out and focus on what I loved, which was writing.

And I had some early success. A few inroads were made with some of my work, but ultimately it wasn’t enough and I tried a number of options to keep myself going for a year, then another, then one more… By the time my daughter was 8, I realized that I needed to alleviate the burdens that had been increasingly placed upon my wife so that I could make my writing pay off, and I began pursuing work in media production again, but this time as a staff member with an established company rather than as the freelancer I had always been. I wanted something that could be counted on, with a salary and a 401K and regularity — things I had not had at my disposal in many years. I had health insurance through my wife’s work, which was actually very good, and for which I would soon be grateful. Continue reading My Story: Lung Cancer and Chemo and a Changed Life →

Sometimes, a Trickle

Cat Videos Have Been Promised

I promised a cat video. But hold on for a moment, if you can, before you hit play. We’ll get to that in a minute. But first, a very brief story about my drive home from a visit with my oncologist.

My car has some problems. It’s about 14 years old, which isn’t all that bad, but it has been through a few of its own tribulations. Let’s just say, it has been roughed up a couple of times, but always managed to come out on the far end, still purring. Lately, though, it seems that the blows may have had a cumulative effect on the poor vehicle’s brain. Which his to say, the central computer is “acting up” a bit these days. But it still runs. I take it in stride. There are hassles, to be sure, not the least of which is that it took me months of jumping through hoops to get smog certification because the machines don’t actually measure emissions anymore — they just grab a code from the central computer. (You may see the problem there.)

But like I said, I take it in stride. The car still gets me where I need to go, and eventually, I hope to get that computer replaced. It isn’t the top item on my list of expenditures yet, but I’m sure it will get there at some point. Hopefully, on my preferred terms and not dictated by the car, but we’ll see. Still, I have a car. It runs. That’s something.

Fear of Fading Vision – Losing Eyesight, or Just Losing Sight of What Matters

Cancer, Fear, Health and Wellness, Reason, , , , , , , ,

I’ve lived with a fear of going blind my entire adult life. As a writer and filmmaker, vision has always seemed essential for my career, an important tool in the creation process. But my father lost the majority of his sight, inexplicably and very slowly, as I emerged into adulthood — his retinas detaching in both eyes with doctors unable to either figure out why or stop the process. Just as my identity as an artist and my career aspirations were taking hold, he was pushed into an uneasy acceptance of his fate that left him bitter, angry, and defiant. I watched this, mostly from afar, and never could shake the question of whether the condition would prove hereditary. Then I became a cancer patient and began chemotherapy, knowing full-well that it very likely would affect my eyesight.

Two days ago, I realized that I couldn’t focus with my right eye.

eyes behind glassesIt’s nothing new for me to have a passing problem with my vision. Yes, my prescription had remained the same for over ten years — my glasses gave me better than 20/20 vision and I was content to wear them, never considering surgery to correct my vision. Six years ago, my daughter had inadvertently elbowed me in my left eye, causing the retina to scar and several ophthalmologists had prepared me for the likelihood that the retina would detach at that time. Admittedly, I was freaked out, and over the course of two years, my retina was heavily monitored as doctors prepared a means of preserving my vision in that eye. The scarring was carefully observed and then it did the most unexpected thing: it healed itself. Where there had been fuzzy abnormalities in the center of my vision, one day everything was more or less clear and back to normal. I breathed a sigh of relief and eventually stopped going back to the eye clinic. My prescription remained unaltered.
