Separate Signal From Noise!

Published on

,

Our lives are increasingly bombarded with unfiltered information (noise) from our busy multimedia environment. Unfortunately, our ancient  brains only actively process about 2% of this incoming information; “dial-up speed in a broad-band world.” Despite this limit, our amazing brains learn continuously, whether we want them to or not. We are always on input at the subconscious level!  Subliminal exposure is an open channel for”unfiltered learning” of ideas and techniques – no “firewall” here.

Internet Buffet: Healthy or Poison?

This “implicit learning,” can easily compromise our carefully created habits and trusted knowlege. Daily environmental exposure (noise) pollutes our brains with unintended and dangerous “alternate truths.” Every pilot (and especially educators) must actively and continuously sort out true signals from noise through honest reflection and analysis. Otherwise, you have the whiteboard of your most valuable truths and skills overwritten with graffiti.

“Cultural contamination” with the latest social media meme – monetized and spread by “influencers” – is almost a comical illustration of how gullible we are as humans. We latch onto the latest clever idea and these have a power of their own to infect less reflective minds. In aviation, bad information and techniques can get you dead quick. Analyzing and coding the real truth—sorting signal from noise—is essential for safety.

The scientific method of verification is a proven tool for analysis and filtering truth. Testing and honest assessment purge the noise. This requires continuous replay, reflection and analysis. And as educators, we must be especially careful to transmit only valid techniques; we are the “aviation influencers.”  Pilots live or die based on the hard, unforgiving laws of nature – “Gravity works!”  As a DPE I hear crazy ideas daily: “A plane cannot stall with the nose below the horizon” (from a private pilot applicant). And worse yet My flight instructor told me that.We need to validate our information carefully with constant reflective analysis.

What’s dangerous is not what you don’t know, its what you ‘know’ that ain’t so”

In a recent blog on training for the initial CFI, the recommended starting point is introspection and analysis of everything you have been learned in aviation: “Step one is reflecting on what you have been taught – knowledge and skills – and comparing it to the actual FAA guidance of trusted/vetted information.” Then as pilots and educators, we must continue to test our knowledge and techniques purging errors and protecting our databank of trusted facts.. This requires honesty, humility and courage. It is essential to remember and accept that we can always be wrong. Approach and suspiciously examine every new “revelation or discovery.”

All the while the world is turning to noise
Oh, the more that it’s surrounding us
The more that it destroys
Turn up the signal – wipe out the noise!

Peter Gabriel, Signal to Noise. 1995

Maintain an Active “BS Detector!”

The human biological system maintains a filter that protects the “self” from the “other” with a fascinating system called the Major Histocompatibility Complex. Every protein in your body is uniquely coded to identify “this is me” and automatically reject “the invader.” (This is why transplanted organs are attacked by our immune system without supression drugs).  We need to develop and maintain a similar active filter on an intellectual level; a “BS detector” to analyze and evaluate the incoming information.

Wrong information can kill you!

Carl Sagan more politely called this essential aptitude the “Baloney Detector,” as a critical component of everyone living in the modern society. Much of what passes for “excellence and expertise,” especially on the internet, is true garbage from beginners pretending to be gods. We all have to protect our true and safe tome of aviation wisdom from the incoming tide of internet crap.

The Power of “Social Proofing”

In our modern world,  our “BS filter” is often compromised bysocial proofing. These are the common testimonials and Yelp reviews attached to products for sale on the internet. Just like “influencers” these lower our defenses and permit easier acceptance of attractive (but usually false) information. Social proofing relies on our gullibility;”If so and so said it it must be true.” Or the “Bandwagon Fallacy:” Judging truth by the number of people who believe it (e.g. how popular is their YouTube Channel). Be very careful who you trust!  CFIs are our modern “aviation influencers” and its important to remember, even they sometimes get it wrong. Otherwise, learners accept, unfiltered, the information a trusted CFI provides with no question. As CFIs, we must be careful to be provide only  accurate, tested, information. That is why our primary source should always be the FAA Handbooks.

Protect the true and safe learning and techniques in your everyday flying. Test and filter out the crap. Fly safely out there (and often!)

Flight test anxiety is one of the most common obstacles to success during an FAA evaluation. It occurs at every level, from initial PPL to jet type ratings! This webinar will offer solutions based on scientific techniques to quiet those test-day butterflies and ensure a better experience. A calm, confident applicant presents their best performance on flight test day!

    “Just because everyone believes it, doesn’t mean it is true.”

    Corollary: “Just because no one believes it doesn’t mean it is false.”

    There are still a lot of old wives tales circulating and being taught by CFIs. The problem is “arguing from authority” in that the pilot states, “My instructor told me so it must be true.” I run into that all the time. Fortunately a hop in the plane manages to put many of these things to rest. Unfortunately I can’t get everyone to take a hop in the plane with me.

    “That is why our primary source should always be the FAA Handbooks.” You are absolutely correct. I only wish it were as easy as you make it sound.

    In the real world, what usually happens is two instructors read the same paragraph in the Airplane Flying Manual . Then when they discuss the paragraph just read, the interpretations come out COMPLETELY opposite. That means, of course, that half of our students get the right answer, and half the wrong one. No wonder you see so many comments on videos where people say they are confused about something.

      Unfortunately, people can watch (or read) just about any form of media (even truthful and accurate), on a superficial level and completely misunderstand the message and meaning on a deeper level. Upon debrief, they cannot provide an accurate “read back” or interpretation (no communication has occurred) Accurate learning is a tricky skill that needs to be developed and continually improved. (as mentioned reflection and analysis should always be applied for accuracy) Some unfortunate people never got even to an to the rote level.

      But I seriously doubt any person, with a sufficient IQ to pilot a plane, can read more than a paragraph (carefully) in the relevant part of an FAA Handbook and tell me “an airplane cannot stall with the nose below the horizon.” This is the sad level of ignorance I can only believe is a result of consuming bad information from clever online “influencers” (presenting inaccurate information with no regard for “truth” or “safety!”) The monetary manipulation behind much of social media is destructive (and as mentioned) subliminally sabotaging real truth at all levels.

        Well, to be honest, I’ve heard or seen comments from pilots with practically every rating, accomplishment, and award possible, and who consider the Handbooks as Bibles, and I don’t think they learned a thing in their Aerodynamics 101 class.
