A scale for measuring Synchronicity

From SusoSight

Synchronicity is when two unrelated events happen around each other. I myself have had so many synchronous events happen to me recently that I've become interested in studying the phenomenon.

This is my attempt to make a scale for measuring the strength of these events.

The first thing to note is that there is a difference between events that you think are synchronous and those that happen as a result of learned behaviour. For example, one morning I thought to turn right to avoid a potential train coming and right at that moment, the train crossing signal went off. Things like this are more likely the result of learned behaviour, because I've seen the train crossing go off in the morning several times, so I've come to expect it.


  • Event A - This is the first event to happen making up the synchronicity.
  • Event B - This is the second event to happen making up the synchronicity.


The following factors can play a role in the scale for measuring syncronicity. This is not finished, but more of just ideas:

  • Timing - How quickly after event A did event B occur. (Closer together means higher on the scale, but also interesting timing can count in positive ways too such as the "exact same time of the year")
    • Within 5 seconds: 10
    • Within a minute: 9
    • Within 15 minutes: 8
    • Within an hour: 7
    • Within 3 hours: 6
    • Within 4 hours: 5
    • Within 6 hours: 4
    • Within a day: 3
    • Within two days: 2
    • Later: 1
  • Role played by observer - Was event A or B triggered by the observer? Event B can't count as much here because you could force a syncronous event. The less the observer has to do with initiating the two events, the stronger the effect.
    • No role played in A nor B, but present at moment: 9
    • Casual role played in A, but not in B: 7
    • No role played in A, but casual role played in B: 6
    • Casual role played in both A and B: 4
    • Deliberately initiated event B after observing A: 1
  • Event rarity - How rare are the two events. If an event happens frequently, then this relationship is not as strong. Running into the same person every day doesn't really count.
    • Something done on an hourly basis: 2
    • Something done on a daily basis: 3
    • Something done on a weekly basis: 4
    • Something done on a monthly basis: 5
    • Something done on a semi-annual basis: 6
    • Something done on an annual basis: 7
    • Something done once every few years: 8
    • Something never done: 9
    • Something never done by anyone: 10
  • Potential Frequency - How frequently is something happening where this event could occur. For instance, seeing two license plates match up on the road may be rare, but because you are constantly driving around other cars, its like "rolling the dice constantly". An example where the frequency is much lower could be when an event happens when you buy groceries. The frequency of that is lower, but regular.
    • Potential events happen daily: 2
    • Potential events happen weekly: 3
    • Potential events happen monthly: 4
    • Potential events happen monthly: 5
    • Potential events happen semi-annually: 6
    • Potential events happen annually: 7
    • Potential events happen every few years: 8
    • First time for observer: 9
    • First time for anyone: 10

Formula for final score: (Timing + Role + Rarity + Frequency) / 4
