It seems that when teams
of doorstep canvassers are sent out to chat with thousands
of residents about same - sex marriage,
swift and durable
change occurs in the opinions on that issue held by
subjects who chatted with a gay canvasser whose script told him to say that he'd really like to get married but the law won't allow it.
The analyst must seek to guard himself against this danger as best he can: in part, by dealing with those situations preferably which are not
subject to sudden
change; in part, by favoring securities in which the popular interest is keen enough to promise a fairly
swift response to value elements which he is the first to recognize; in part, by tempering his activities to the general financial situation — laying more emphasis on the discovery
of undervalued securities when business and market conditions are on a fairly even keel, and proceeding with greater caution in times
of abnormal stress and uncertainty.»
