How do you measure complexity.
- We know it when we see it, we recognize design, since it was cognized.
When digging in the ground we come across buried ancient pottery. We know it was designed. How? Because we have seen a modern comparative object that we know is designed. We do not measure in this case, we infer the design.
Is an octopus designed? We have no agreed designed object to compare with an octopus. Some people will say, “It looks designed to me,” and others will say, “It evolved and was not designed.” This method only works when there is an agreed equivalent to the modern designed pottery.
It is not a way to
measure complexity, as the thread title asks.
SETI measures design by comparing background noise with a measured emergent signal of some persistence.
Again, we know that most background noise is natural, not designed. However, not all non-background signals are designed. When the first pulsar was discovered, one of the hypotheses considered was the LGM hypothesis: Little Green Men. In effect a design hypothesis. Despite not being part of the background noise, the pulsar signal was determined to be of natural origin and a satisfactory non-design explanation found: a rotating neutron star.
This example also fails to provide a
measure of complexity. It is a valid way to pick out any interesting signals from the background, but it is not of any use in proceeding beyond that to determine whether or not the unusual signal is designed or not.
It is also worth pointing out that in some cases, often in cryptography or secure communications, signals are designed to appear as random background noise – steganography for instance. Some background noise is designed, just as some non-background signals are not designed.
We are still awaiting a way to measure complexity.
