There was no fitting image for this post so – what the heck – I’ve just used Juliette again. If nothing else that’ll tempt you into wading through my prose.

I’ve noted how media critics of “conspiracy theories” aren’t just opposed to grandiose, unfounded claims but to suspicion of official or quasi-official narratives. Here are some notes on how the charge of “conspiracy theory” works to discredit this scepticism.

For example, with regards to the Pan Am attack, Geoffrey Robertson wasted no time in dismissing sceptics of Megrahi’s guilt…

If Megrahi was guilty of the Lockerbie bombing (and, conspiracy theories aside, the evidence justified the verdict), then Gaddafi must have given the order…

I will say this for Robertson: he’s remarkably efficient. What’s the point of explaining the biased procedure, dodgy witnesses and meager evidence of the prosecution when you can dismiss all scepticism as the work of minor nutjobs?

Reading mainstream coverage of dubious events you’d almost think that curiosity is the preserve of eccentrics. After the still-mysterious death of Gareth Williams, say, a Guardian reporter claimed it was among the “unexplained deaths that fuel conspiracy theories”. Not an unexplained death that calls for an explanation: a strange thing for strange people. The effect of this is to consign parapolitical investigation to the fringe; beyond respectable discourse. Kooky stuff. File it under “esoterica”.

This is evident when, er – “theorists” are promoted. The focus isn’t on their criticism of established theories but the narratives that some of them are propagating. I’m sure you’ve seen plenty of stories on Loose Change, for example, but there’s a decent chance you’ve never heard of Press for Truth. The Beeb put out a hit-piece on a smorgasboard of speculation titled 7/7: The Ripple Effect but didn’t talk with someone like Nafeez Ahmed. I’ve nothing against people constructing theories if they have the evidence to bolster them but the impression one receives is that there are two narratives: the accepted one and its conspiratorial opposite. Doubt isn’t an option.

The charge’s effectiveness as a tool for bullying critics of the powerful can be evidenced by their enthusiastic use of it. How did the U.S. government defend itself from opponents of Depleted Uranium? They accused them of being conspiracy theorists. How did Margaret Chan hit back at critics of WHO’s links with Big Pharma? She charged them with being conspiracy theorists. How did Blair treat his critics over the Iraq invasion? He said they were – well, I’m sure you can guess the rest.

How this trend developed is an interesting question. I might write a book on it. That’s not an idle threat.
