Extraordinary claims require extraordinary evidence?

January 13, 2014

Some time back I went to La Trobe university and presented on the topic ‘Why I love Richard Dawkins, but am not an atheist’. In this talk I spoke a lot about evidence and point to the evidence for the historicity of the resurrection of Jesus from the dead. This talk often stimulates lively and worthwhile question/discussion time.

I enjoyed discussing this topic with one particular person who challenged my presentation on the ‘evidence’ for a resurrection from the dead. As a part of his challenge he used a fairly familiar and popular test for assessing evidence: ‘extraordinary claims require extraordinary evidence’. This quote originated with Carl Sagan and has become quite popular in assessing ‘extraordinary’ claims. I even noticed the ‘extraordinary claims require extraordinary evidence’ was featured in a recent Arthur episode (assessing whether giant worms were going to attack the neighborhood).

I initially accepted Sagan’s test as legitimate and I then proceeded to share why I felt the evidence for the historicity of the resurrection was extraordinary, but upon further reflection I’m not so sure I’d be so quick to accept this test as legitimate.

Whilst I do think that the evidence supporting the resurrection of Jesus from the dead (and the historical reliability of the New Testament) is quite extraordinary – the very fact that we’re still talking about the enduring influence of a Galilean itinerant preacher who lived 2000 years ago seems extraordinary to me. But as I reflected on the claim, ‘extraordinary claims require extraordinary evidence’ I’m more and more convinced that this is misleading.

It’s misleading because it creates a subjective category when assessing evidence, i.e. ‘extraordinary’. How extraordinary is extraordinary? How do you measure ‘extraordinaryness’? In our discussion this was made clear when I asked, ‘well, what evidence would convince you?’ I was left with no satisfactory answer. The questioner had no clear idea of what would constitute ‘extraordinary’ evidence to accept the resurrection of a person from the dead. It almost seems to me that this claim is used  as an excuse to not accept the evidence that is rallied to support a miraculous claim (notably the resurrection of the dead). It seems to me this way because no evidence will ever be extraordinary enough to convince someone that a dead person came back to life again.

I would suggest a better statement would be ‘extraordinary claims require evidence’. If there is evidence for a particular event, then that evidence needs to be acknowledged, weighed, and considered. I don’t think the evidence necessarily needs to be ‘extraordinary’ – it just needs to be reliable. If the evidence for an extraordinary claim is adjudged ‘reliable’ then the extraordinary claim should be accepted.

I would go on to suggest that the evidence we have for the resurrection of Jesus is in fact reliable and hence this is why I accept this quite extraordinary claim.

  1. This is just silly, of course extraordinary claims require stronger evidence than mundane claims. Would you accept the same amount of evidence to the claims of “I have a pet dog” and “I have a pet unicorn”?

    • Erm, I think I would. What evidence would satisfy you that I have a pet unicorn? Surely it would be visiting and showing you the animal wouldn’t it. I think the burden of evidence would be the same in each. That illustrates my point precisely – there is nothing extraordinary about that particular ‘type’ of evidence. It’s just reliable evidence that matters.

      • I think I would want to inspect a unicorn in person much more carefully than a dog.

      • Sure, but “inspecting” a unicorn is hardly extraordinary is it? (the inspecting part not the unicorn – I’d admit if you had a pet unicorn it would be extraordinary)
