Bernie’s Rule of Business Predictions and Time Frames

There are generally four time frames used when business people are making predictions:

  • in a year
  • next 1-2 years
  • next 3-5 years
  • next 5-10 years

If you see a business person making such a prediction, this is what they mean:

  • in a year: the prediction will happen
  • next 1-2 years: the prediction should happen
  • next 3-5 years: the prediction could happen, but not soon
  • next 5-10 years: they have no idea!

For any business prediction, the time frame determines the probability. If they say in a year, they either are doing it themselves or someone they know is. If it is 1-2 years, it won’t happen this year, but someone is working on it. If they say 3-5 years, then it’s likely not in progress, but there is talk of working on it.

The only prediction that is useless is 5-10 years. If someone says 5-10 years, they are saying something like “I don’t want to say it will NEVER happen, but it is not even close to coming to fruition, so I will predict 5-10 because who is even going to come back and ask me about it in a decade from now?” 🙂

Something to bear in mind the next time you hear a business prediction.

How long are you going to live? Now you can find out


According to this, you have two very good rules of thumb or models you can use to determine this:

1) The heuristic bi-linear model. We made this by making the best bi-linear model a bit simpler to apply.

It goes:

If you’re under 85, your life expectancy is 72 minus 80% of your age.

Otherwise it’s 22 minus 20% of your age

2) The 50-15-5 model. This one asks you to remember some key values and then to interpolate between those values. It goes:

The life expectancies of 30, 70, 90 and 110 year olds are about 50, 15, 5, and 0.
