Theories and Facts about Santa Claus

My friend Alom Shaha recently scripted the video above to try to explain the concept of ‘a scientific theory’.

I like the video, but I feel one point gets lost. And that is that  ‘theories’ are like ‘plot lines’ in a TV detective programme – they link together ‘the facts’ to tell ‘a story’.

Example#1: Café Mimmo

• I am observed at 10:15 a.m. leaving my house on Church Road
• I am observed at 10:21 a.m. at the junction of Church Road and Walpole St.
• I am observed at 10:27 a.m. near to Café Mimmo on Broad Street.
• I am observed at 10:28 a.m. in Café Mimmo on Broad Street.
• I am observed at 10:58 a.m. walking North on Church Road.

These are ‘the facts’. But what is really going on? Is there a ‘story’ that links all these facts together? Let me propose a theory:

• Theory: Michael goes for coffee every day at Café Mimmo

This theory links all these facts i.e. it explains how they relate to each other.

If this is a good theory, it ought to be able to predict new facts – and these predictions could then be checked.

Notice that the theory doesn’t specify the route I take to the Café. So even though the theory explains why I was seen on Church Road, it doesn’t predict that I always will be.

But the theory does predict that I will go to Café Mimmo every day. This could be easily tested. And if I didn’t visit every day, the theory could either be invalidated, or it might need to be revised to state Michael goes for coffee most days at Café Mimmo

I am sure you get the idea. But notice how the theory is simpler and more meaningful than a large number of facts. Facts tells us ‘what happened’, but theories tell us ‘what’s going on’.

Example#2: Santa Claus

• On Christmas Day (usually, but sometimes on Christmas Eve) children all around the world receive presents.
• On Christmas Eve parents leave out gifts – typically whisky (please) and a carrot – and these gifts are at least partly consumed by the morning.

These are ‘the facts’. But is there a theory that links these facts together? In fact there are two theories.

The traditional theory is that a mysterious being known as ‘Santa Claus’ delivers the presents on a sleigh pulled by flying reindeer and filled with an improbably large bag of toys.

Alternatively, some people contend that there is a vast conspiracy in operation in which otherwise honest and rational parents consistently lie to their children, year after year. According to this theory, it is in fact parents that buy all the presents, and fabricate forensic evidence of a visit by the fictional being ‘Santa Claus’.

The traditional theory has been heavily criticised, largely due to the unknown identity and quasi-magical abilities of the ‘Santa Claus’ figure.

However, I have never been a fan of conspiracy theories – they always seem rather unlikely to me. In particular I am sceptical that millions upon millions of parents would systematically lie to their children. I would never do such a thing.

So I will leave it up to you to imagine experiments that you could perform that would help to decide which theory is in fact correct.

One obvious experiment is to stay up late on Christmas Eve and watch for the arrival of ‘Santa Claus’.

But can I please ask you to be careful: Santa Claus is known never to bring gifts to boys and girls that don’t go to sleep at night. So use a webcam.

But whatever you believe: I hope you have a Happy Christmas 🙂

My son Alexander told me that if he had a webcam he’d be setting it up to test his new this year hypothesis that I am Father Christmas. What I find very interesting in this is that Father Christmas has told me that he will be getting Alexander a “video editing suite” for Christmas, including the necessary webcam. Unfortunately it will arrive a day too late for him to test his hypothesis!

Now that is a scientific attitude – shame he will be just too late to finally confirm the traditional theory and conclusively disprove this ridiculous conspiracy theory.

Happy Christmas to you all.
