validate

例句：

Much more important in economics, however, are panics that, whatever sets them off, validate themselves—because the panic itself makes panic justified. （摘自保羅．克魯曼（Paul Krugman）寫的《面對失靈的年代：克魯曼談金融海嘯》（The Return of Depression Economics and the Crisis of 2008））

但在經濟學的領域中，遠為重要的是不管什麼事情引發恐慌，最後竟然弄假成真──恐慌本身使得恐慌言之成理。
