How your gadgets are turning you in to an addict. Damian Thompson

      When our hand creeps out towards yet another square of organic chocolate, or when we play just one more game of Angry Birds before setting off for work, or when we check a secretly bookmarked porn site for new arrivals, we’re behaving like addicts. The activity in question can be innocent or shameful. Either way, it reinforces the addictive streak in human nature.

      That streak is there because our brains have evolved to seek out immediate, short-term rewards. Our ancestors needed to stuff themselves with energy-rich berries and to respond quickly to sexual stimulation; we wouldn’t be here if they hadn’t.

      Our problem is that we’ve built an environment that bombards us with rewards that our bodies don’t need and that do nothing to ensure our survival as a species. Yet, because they are rewards – that is, because they provoke specific feelings of anticipation and pleasure in the brain – we grab them anyway.

      To put it another way, we reach out for a fix.

      That’s a word we associate with helpless addicts. They talk about their ‘fix’ because it feels as if they’ve temporarily fixed themselves when they take their drug of choice. There’s no mystery about this. As a result of heavy exposure to the drug, they have become dependent on frequent chemical rewards. Their brains are in a state of hypervigilance, waiting for the blessed relief of a chemical that, once tolerance develops, merely allows the addict to feel normal, as opposed to anxious and ill.

      That much is not in dispute. Many addiction specialists go further, however. They say that the brains of addicts are fundamentally different from those of non-addicts. They are forced to chase these rewards because they have ‘the disease of addiction’.

      I want to challenge that theory. I suggest that, if you keep eating chocolate biscuits until you feel sick, you’re indulging in a milder version of the addictive behaviour that leads heroin addicts to overdose. I’m not equating the two situations, of course. I’m suggesting that they lie at different points on a spectrum of addictive behaviour on which everyone can be located.

      Also, and more importantly, many of us are being pulled towards the dangerous end of the spectrum, thanks to technological and social changes that stimulate the most fundamental of all our instincts – desire.
