怎么一出新款手機(jī)，你的舊手機(jī)就“恰好”被摔壞了？其實(shí)，這可能是“升級效應(yīng)”所致。

If you've dropped, shattered or misplaced your phone more than usual in recent months, there could be a good reason.
如果你近幾個月比平時更容易掉手機(jī)，摔壞手機(jī)，或者把手機(jī)放錯位置，那你可能真的有充足的理由。

Scientists claim that as soon as a new phone comes out, people tend to act recklessly with their existing phones - without even realising it.
科學(xué)家表示，一旦有新款手機(jī)面世，人們對現(xiàn)有的手機(jī)就更加“肆意妄為”，而自己根本意識不到。

Researchers believe this is because we are conditioned to avoid the guilt of upgrading to a more expensive model without proper justification.
研究人員認(rèn)為，這是因?yàn)槿藗兿乱庾R地為自己給手機(jī)升級換代找個理由，以避免“罪惡感”。

They've labelled this phenomenon the 'upgrade effect'.
他們將這種現(xiàn)象稱之為“升級效應(yīng)”。

'We would feel guilty about upgrading without a reason - but if our current product were damaged or depleted, we'd have a justification to upgrade without appearing wasteful,' said Columbia Business School Professor Silvia Bellezza.
哥倫比亞商學(xué)院教授西爾維婭說：“沒有理由就給手機(jī)升級換代，我們會感到罪惡。但如果你現(xiàn)在的手機(jī)壞掉了或者不好用了，我們就有理由換手機(jī)，而且看起來不浪費(fèi)?！?/p>

'So, we use our phone in the rain or leave our laptop behind at airport security without being aware that our carelessness has an underlying motivation.'
“所以我們會在雨中使用手機(jī)，或者把筆記本電腦落在機(jī)場安檢那里，卻意識不到我們的粗心其實(shí)有潛在的動機(jī)?！?/p>

By tracking the figures for the iPhone 5 and iPhone 5S, the group found that as soon as the 5S was released, iPhone 5 owners spent less time looking for their lost phones.
研究人員還追蹤了iPhone 5和iPhone 5S的數(shù)據(jù)，結(jié)果顯示，當(dāng)iPhone 5S發(fā)布后，iPhone 5的失主就不再熱衷于尋找自己丟失的手機(jī)。

The team also looked at an online survey of 602 mobile phone owners and found that the availability of an upgrade would lead to product neglect.
另外，研究小組還對602名手機(jī)用戶進(jìn)行了在線調(diào)查，發(fā)現(xiàn)有新款手機(jī)上市時，大家對舊手機(jī)就不那么在乎了。
