Astrology is a set of systems used for attempting to better understand the past and present and for predicting the future based on the idea that there’s a relationship between the position of stars and planets in the sky and events in the life of a person. A system of astrology can be as basic as the newspaper horoscope, which categorizes all people into 1 of 12 categories. Across most of human history, astrology was widely considered a scholarly discipline. It was accepted as scientific fact in government and academia from early civilization up to at least the 17th century.
The Myers–Briggs Type Indicator (MBTI) is a psychometric assessment based on a simple questionnaire derived from the idea that there are 4 and only 4 principal psychological functions by which people experience the world. The intent is to measure and predict how individuals perceive the world and make decisions, categorizing all people into 1 of 16 categories. The Myers-Briggs is used by 89 of the Fortune 100 companies and is very popular in businesses around the world; however, it has been criticized as having methodological weaknesses, poor statistical validity, and low reliability.
The Myers–Briggs assessment is no better than astrology, and potentially much worse.

If you know me (and if you’re bothering to actually read this blog, there’s a good chance that’s true), you know I’m an aviation “enthusiast,” to put it mildly. I won’t publicly admit I’m crazy about aviation because the FAA might ground me for mental health reasons, but I’m sure you can draw your own unscientific and unproven-in-a-court-of-law conclusions. I love to fly. I love to fly because you can’t beat the views. I love to fly because it takes skill and concentration but is simultaneously exciting and relaxing. I love to fly because I can take day-trips to places it would take others a weekend to make.
When I try to share my “passion” for aviation, it’s not uncommon for me to hear responses like:
That must be fun, but flying is really expensive, right? I mean, I’ve heard aviation gas is really pricey.
I worry sometimes that folks are using the assumption of avgas price as an excuse to never consider learning to fly. Becoming a pilot, of course, is not for everyone; and yes, avgas costs more per gallon than car gas; but it’s an apples-to-oranges comparison.
To help illustrate, let’s look at the fuel and time costs for cars versus airplanes. The devil’s in the details, they say, so I’m going to use a whole bunch of averages and assumptions I pulled from some quick Google searches.
Exact results will vary, of course; but to get things started, let’s list out my assumptions:
- Traveling as a family of 4
- 2 adults
- 1 teenager
- 1 less-than-6-year-old
- Driving at posted road speed limits for the route
- Fuel burn is 23.6 miles per gallon (national average)
- Gas is $3 per gallon (national average)
- Flying an average (and extremely common) Cessna 172
- Cruising at 140 mph
- Burns about 9 gallons per hour, so we’ll get about 15.5 miles per gallon at cruise speed
- Avgas is $5.20 per gallon (national average)

The road to a dormant blog is paved with good intentions. I had all sorts of opportunity over this last year to write, but something or another more important always usurped priority. Even more so, I had no shortage of topics with which to opine. There were many aviation trips, numerous adventures with my family, and a plethora of ideas to investigate. One such family adventure involved one of the shortest aviation trips we’ve ever taken and raises to mind some ideas about natural overreaction as a standard response.
This story begins, as many of my stories seem to the last couple of years, with a flight in our airplane. It was a beautiful summer afternoon, or more specifically: Saturday, June 14. (I love flight logbooks.) We didn’t have a lot of time that day, so we decided to hop in the airplane and make a very short trip from Bremerton National to Longlake, a trip so short you hardly get into a cruise configuration before you need to setup for descent. It was just an excuse to enjoy the water on a summer afternoon.
Our airplane is a boat-plane amphibian without floats, so it sits fairly low in the water. This is me in displacement taxi on Longlake:
We came in for a landing toward the south end of the lake, and we were down and into idle-power displacement taxi in a few seconds, having only consumed the bottom quarter of the lake surface.
