Approaching scientific literature sensibly Ken Perrott Jun 25

thinking-conf-bias

We all suffer more or less from confirmation bias – it is just human.  So it’s natural for people to be selective, and to indulge in some cherry-picking and biased interpretation, when quoting scientific literature to support an idea they promote.

pseudoscience-cherry-picking

In the scientific community peer review and continual submission of ideas to scrutiny by colleagues helps keep this under control. But it can really get out of hand when used political activists use the literature to support their claims.

I have got used to anti-fluoride commenters on social media simply citing a paper or even providing a bare link, without comment, as if this somehow makes their claims irrefutable. Perhaps, in truth, they have not even read the paper they cite, or understood it, so do not feel confident discussing it.

But this tactic is particularly lazy – and stupid. To simply give a Google Scholar search as proof. Lately I have been presented with links to such searches to argue that fluoridation is toxic. Just a search for “fluoride toxicity.”

This is what that search produces – 234,000 hits:

Fluoride toxicity – 234,000 results

fluoride-toxicity

Sounds good to the uninitiated, I guess. It does seem to produce a large number. But does that mean anything?

What about searching for water toxicity. This produces over 2 million hits. Are we to assume from this that water is toxic, seemingly 10 times more toxic than fluoride?

Water toxicity – 2,190,000 results

Yes, I know some social media do not offer much space for commenting but that should not be an excuse for such silly citations.

A healthy attitude towards quantum mechanics Ken Perrott Jun 19

No Comments

Apparently the above quote “You can safely ignore any sentence that includes the phrase’ according to quantum mechanics” is used by Robert P. Crease and Alfred Scharf  in their upcoming book The Quantum Moment: How Planck, Bohr, Einstein, and Heisenberg Taught Us to Love Uncertainty.

Good advice.

What makes something right or wrong? Ken Perrott Mar 20

Here is another of the  4 animated videos produced by the British Humanist Association. They are all narrated by Stephen Fry.

This one deals with aspects of morality – an important subject where the voice of non-theists is often ignored.

Another god debate Ken Perrott Feb 23

No Comments

GodAndCosmology_Slider

Apparently Sean Carroll and William Lane Craig went head to head this weekend on the question of “the existence of God in light of contemporary cosmology.”

Usually I think these sort of debates are a waste of time but am keen to see the video of this one – it will be on Youtube eventually. In previous debates Craig attempts to use cosmology to “prove” the existence of his god (I use the word “use” as meaning very opportunist use of motivated reasoning). In most debates his opponents are usually not completely familiar with modern cosmology and he gets away with murder in his misrepresentation of the science.

But Sean Carroll is a different proposition. Not only is Sean a researcher and teacher in cosmology he is also an excellent communicator of science. His recent bookThe Particle at the End of the Universe, won last year’s Royal Society Winton Prize for best science book (see The particle at the end of the universe’ wins Winton Prize).

Carroll

Nor is he intimidated by Craig’s acknowledged debating skills. He says in a blog post before the debate:

“You can find some of WLC’s thoughts on the upcoming event at his Reasonable Faith website. One important correction I would make to what you will read there: Craig and his interlocutor Kevin Harris interpret my statement that “my goal here is not to win the debate” as a strategy to avoid dealing with WLC’s arguments, or as “a way to lower expectations.” Neither is remotely true. I want to make the case for naturalism, and to do that it’s obviously necessary to counter any objections that get raised. Moreover, I think that expectations (for me) should be set ridiculously high. The case I hope to make for naturalism will be so impressively, mind-bogglingly, breathtakingly strong that it should be nearly impossible for any reasonable person to hear it and not be immediately convinced. Honestly, I’ll be disappointed if there are any theists left in the audience once the whole thing is over.”

I think his tongue was in his cheek with the last sentence.

His suggestion for viewers:

“Feel free to organize viewing parties, celebrations, discussion groups, what have you. There should definitely be a drinking game involved (it’ll be happy hour on the West Coast, you lightweights), but I’ll leave the details to you. Suggested starting points: drink every time WLC uses a syllogism, or every time I show an equation. But be sure to have something to eat, first.”

Thanks to God and Cosmology Debate with W.L. Craig

Testing the God theory Ken Perrott Dec 04

I enjoyed this video.

It is a full lecture but well worth watching – especially if you are interested in the science-religion debates.

Sean Carroll presents these cosmological arguments well – and his analysis is far more up to date – and “with it” than those theologians who venture into the area. Just compare this with the rubbish W. L. Craig comes out with.

This lecture really puts the theological argument that God is a “better explanation” of life than the multiverse into perspective.

Thanks to Your Thanksgiving viewing « Why Evolution Is True.

‘The particle at the end of the universe’ wins Winton Prize Ken Perrott Nov 27

No Comments

Congratulations to Sean Carroll – the winner of the 2013 Royal Society Winton Prize for science books.  (see Higgs boson book scoops Royal Society Winton Prize).

His book, The Particle at the End of the Universe, beat 5 other excellent titles. and the Judges were unanimous in their decision.

The book was also recently reviewed by Richard Easther on SciBlogs (see The Higgs, the Universe and Everything).

I was very impressed with his last book, From Eternity to Here, so I am very much looking forward to reading this one.

Here is a short video of Sean reading from his book before the announcement.
‘The particle at the end of the universe’ by Sean Carroll.

Sean Carroll is a great science communicator. He participates in, and organises, some great on-line discussions of science and philosophy. He also manages a  science blog  - have a read of his own comments on the Winton Prize. In these he reminds us not to forget the other excellent books on the shortlist:

I wouldn’t have wanted to be on the prize jury, however. All of the six shortlisted books are fascinating in their own ways, and at some point it’s comparing apples to pears. I wouldn’t have been surprised if any of the other contenders had walked away with the trophy:

These books are also being reviewed on SciBooks. See Birds’ Own Stories Captivate for a review of Tim Birkhead’s book.

The recent Science Weekly podcast has a great discussion of all the books shortlisted for the Winton prize. In it two of the judges speak really enthusiasticly about all these books – and some that didn’t make the shortlist. Really makes we want to get all the books on the list and get stuck into reading them straight away.
