Ask Stephan Lewandowsky anything, except “please can I have that data”.

Good news, according to The Guardian Stephan Lewandowsky is doing Reddit/Science Ask Me Anything session (finished for today, but back again tomorrow).

Richard Tol asked Stephan Lewandowsky how he felt about data. Stephan Lewandowsky replied with exactly the right answer, saying it’s crucial, and “I release all relevant data immediately”. Then Barry Woods quoted the Vice Chancellor of UWA refusing to provide Lewandowsky’s data (after many requests). Apparently it is UWA practice not to release data, no matter how many times researchers politely enquire. How unfortunate for Stephan to have worked at such a backward institution?

Strangely,  Barry Woods comment disappeared completely. (Lucky there’s a screen-shot.)

There must be something wrong with the server at Reddit, surely? Nonetheless Stephan Lewandowsky is passionate about data, I’m sure he will fix this as soon as possible in the morning. (Actually he is probably emailing Stephen McIntyre this minute). It could all be solved so quickly.

Of course, it is too late for him to call the Vice Chancellor, so it may take til lunch time tomorrow to change UWA’s data hiding practice.

We look forward to advancing cognitive science with open data too Professor Lewandowsky.



The Reddit Comments


Please elaborate on the importance of reproducibility of research, including the availability of data and background data to other researchers if not the public, and on the importance of instilling this attitude in our PhD students.

StephanLewandowsky Professor of Cognitive Science

Crucially important. That’s why I release all relevant data immediately upon publication. I also have now begun to preregister my experiments, which i consider to be an exciting new development in the social sciences. I am also now increasingly relying on Bayesian statistics for similar reasons. Finally, I have rarely published anything without knowing that it has replicated (e.g. my two recent papers on conspiratorial thinking and the denial of science).

Barry Woods:

In this case will you be providing the data that was requested for – NASA faked the Moon Landing, therefore [climayte science] is a hoax, Lewandowsky et al, Psychological Science

The Vice Chancellor of UWA has refused to release it.

Mr B. Woods

Dear Mr Woods,

I refer to your emails of the 11th and 25th March directed to Professor Maybery, which repeat a request you made by email dated the 5th September 2013 to Professor Lewandowsky (copied to numerous recipients) in which you request access to Professor Lewandowsky’s data for the purpose of submitting a comment to the Journal of Psychological Science.

It is not the University’s practice to accede to such requests.

Yours faithfully,
Professor Paul Johnson,

Do you regret Paul Johnson’s statement.

I wish to submit a comment to the journal with respect to a factual error in the paper’s methodology. The Raw survey data, is required (should it contain referring domain information) to establish who exactly is right or wrong.
