Appropriate Treatment Good; Inappropriate Treatment Bad

By Erik Meira

Ok. So you know that I don’t like the idea of defining the world as “Good Things” and “Bad Things”. I also generally don’t like politics and advertising. Both have the one goal of defending a position no matter what. I’m just not a fan of blind promotion. It really leaves you open to the false dilemma fallacy.

Even though I am a physical therapist, I am not a fan of blind promotion of physical therapy. I think it hurts the profession more than it helps. More importantly, it hurts patients. [...]

Getting Rid of Something Positive

By Erik Meira

That title is a little misleading. Remember “positive” does not mean “good” when we talk science. It means “additive”. In my opinion, physical therapy is most effective at removing something positive from our patients. Let me explain… [...]

Does Experience Matter?

By Erik Meira

Yes. Experience matters. Thanks for reading! I’ll look for your comments below…

Of course I’m kidding. I turned off the comments long ago – the last people that I want to hear from are the loons on the internet. Before I go any further, I need to give props to Joe Brence for his recent post on Forward Thinking PT last week regarding experience for getting me going on this again. If you ever attend my weekend course, you will notice that I include this in my science intro so it’s a topic I discuss often. [...]

Inflation, BICEP2, and the Primordial B

By Erik Meira

On Twitter I retweeted a link that shows Assistant Professor Chao-Lin Kuo surprising Professor Andrei Linde with evidence that supports cosmic inflation theory. He needed to sit down after hearing the news. This recent scientific discovery has made finding evidence of the Higgs boson seem like a pile of puke! (I know that doesn’t make sense.) You may be hearing about giddy astrophysicists mentioning that this is a guaranteed Nobel Prize if it later gets corroborated by independent observations. So what exactly did they find and why is it such a big deal? As with the evidence regarding the Higgs, this is another example of how science works and how speculation means nothing without hard evidence. [...]

Could You Be Wrong?

By Erik Meira

We all have beliefs – there’s nothing wrong with that. We also all have prejudices, biases, etc. Not ideal, but that’s the reality. With some appropriate critical thinking, you can keep those at bay. Now, is it possible that your beliefs are wrong? Any self-respecting scientist would say, “Absolutely!!!”…and that is true of EVERYTHING that you believe. You could always be wrong.

So how accurate are your beliefs? Have you been a slave to confirmation bias and your prejudices or are you being honestly critical? How will the future view your beliefs? Will you find out later that you were wrong, really wrong? As a medical provider, will you find out that you were advising patients with grossly inaccurate information? Well, psychology research has looked at this and it turns out, you can accurately judge the quality of your own beliefs… [...]

Does Positive Mean What You Think It Means?

By Erik Meira

When chatting with others, we all understand what someone means when they say positive or negative. Positive usually falls in line with the idea of the “bright side” as in being an optimist and having a positive attitude. Negative on the other hand usually refers to the idea of the “dark side” as in being a pessimist and having a negative attitude.

Although these are examples of proper uses of these words, thinking about them this way can be confusing when trying to apply them in scientific discussions. For example, whenever I hear someone say something like, “I am a big believer in positive reinforcement,” I know that that person doesn’t know what they are talking about… [...]

When a Valid Argument Can Be False

By Erik Meira

“That’s valid,” you say, but what do you mean by that? A single statement can be valid by itself if it is a previously proven “truth”, but what about an argument? You remember arguments, right? Premise, premise, therefore conclusion? Funny thing about valid arguments, they have nothing to do directly with truth. Arguments can be valid and false at the same time, just as they can be invalid and true at the same time. What?

Since deductive arguments are the basis of all research, you need to understand this concept. I have quoted before on a podcast, “A flawed study is still a flawed study regardless of p-value or level of evidence.” Here’s how!

Why I am not a Manual Therapist

By Erik Meira

Read that title! Here comes Erik again, with all his manual therapy hate and negativity! *Sigh* This is not an attack on manual therapists, it is a defense of NOT being a manual therapist. In other words, it’s not all about YOU and what YOU ARE. It’s about ME and what I’M NOT. Quick disclaimer: This is going to be long format. You are a busy person and might have already made up your mind, so you probably shouldn’t read it. This is more about me just pulling back the curtain a little bit. [...]

Uncertainty and The Simple-Minded

By Erik Meira

I’ve written in a previous post that reality keeps us from being 100% certain of any “truth”. This is why we have science and its flaming laser sword of falsifiability. But why is this such a tricky concept for humans to grasp? And what about uncertainty? Is there room for uncertainty in science? Sure! Science is very comfortable with uncertainty! [...]
