Understanding The Arbitrary Signs

In my post, “Leadership Echolocation: How Big Are Your Ears?” I spoke about the Ladder of Inference. The idea is that we can’t help but try to make meaning of things. It’s how our human minds work. I thought it was genius how G. K. Chesterton worked this into one of the Father Brown Stories. He wrote, “The letter, however, was in cypher; and one very hard to follow, having been invented by children. Does that strike you as paradoxical? Don’t you know that the hardest signs to read are arbitrary ones? And if two children agree that ‘grunk’ means bedtime and ‘splosh’ means Uncle William, it would take an expert much longer to learn this than to expose any system of substituted letters or numbers.” In that passage, Chesterton highlighted an interesting paradox about ciphers and codes. While we often think that a complex or unfamiliar code would be harder to decipher, Chesterton, through Father Brown, argued that codes invented by children—simple, arbitrary signs—are actually more difficult for experts to decode because they lack an obvious logical pattern.

Children can create entirely arbitrary symbols for meanings like “bedtime” or “Uncle William,” these signs don’t follow any predictable rule. An expert trying to uncover the code would have to test many possibilities, which could take longer than simply recognizing that it’s a straightforward substitution system (like replacing letters systematically).
This idea underlines a key point: the perceived complexity of a cipher or language isn’t necessarily related to how many symbols it uses or how intricate it looks, but rather how predictable or patterned those symbols are. Arbitrary signs, despite their simplicity or randomness, can be the most challenging precisely because they defy the brain’s natural tendency to find meaning through patterns.
Now let’s connect this to Chris Argyris’ The Ladder of Inference model which described how individuals move from observable data and experiences to taking interpretive leaps—often jumping to conclusions without fully examining the data. When it comes to symbols or signs, humans tend to attach meaning based on their assumptions, biases, or patterns they recognize, sometimes skipping critical steps in understanding.
In the context of arbitrary or seemingly random symbols, the difficulty lies in the lack of clear data or patterns that can be reliably interpreted—making the “climb” up the ladder more challenging or even leading to false inferences. The symbols’ randomness prevents us from confidently moving through the rungs of the ladder, highlighting how our interpretive processes depend heavily on the clarity and structure of the data we observe.
So, if we’re trying to interpret arbitrary signs without sufficient context, we might prematurely jump to conclusions, which aligns with Argyris’ concept that our inference process can lead us astray if not carefully managed. Recognizing this can help us be more mindful of how we form beliefs and understand symbols that are inherently ambiguous or patternless.
