True. It might be because the research has not involved empirical tests of any such practical information, as far as I could tell from the article.

My vague takeaway is that burglars rely on patterns of typical household layouts and homeowner behaviors so that they can do their work, as it were, at a higher level of abstraction than an amateur can. Anything that you can do to frustrate their assumptions of typicality, then, might lower their efficiency or discourage them from attempting a burglary in the first place. Perhaps some clever applications of home automation tech could be employed. Or if you're fortunate enough to keep an inconsistent schedule, that too could help.
