Google’s search is so effec­tive at find­ing infor­ma­tion that it’s changed what we choose to remem­ber, accord­ing to Friday’s issue of the jour­nal Science.

When we are aware of where to find infor­ma­tion, we’re less like­ly to remem­ber it, some­thing called “The Google Effect” by lead psy­chol­o­gist Bet­sy Spar­row of Colum­bia University.

The study asserts we’re not becom­ing less intel­li­gent but the ubiq­ui­tous search engine appears to be chang­ing how we remem­ber things. For many of us, we’re hap­py to for­get rote infor­ma­tion, know­ing that it can be retrieved using a search engine.

Google’s search engine is amaz­ing con­sid­er­ing that it index­es mil­lions of web pages and still pro­vides with you with good results. In June alone, web surfers used Google 11.1 bil­lion times, accord­ing to the web site Search Engine Watch.

From what I’ve seen, the search that’s avail­able in a main­stream Help Author­ing Tool (HAT) isn’t near­ly as effec­tive. And if your users are used to results pro­vid­ed by Google (and who isn’t?), the search in online help is bound to disappoint.

Still, even Google’s search engine has its lim­its. Ear­li­er in the year, Forbes pub­lished an arti­cle called “Google Finds No Friend In Face­book As Social Sur­pass­es Search” that states, “Face­book became the most vis­it­ed site in the U.S. for the first time sur­pass­ing Google and Yahoo.” Author Anne Gen­tle wrote in her blog: “…you are more like­ly to get use­ful links by ask­ing your friends and col­leagues about cer­tain top­ics than you are going to get them by search­ing on Google.” That’s prob­a­bly why Google just launched Google+, a social net­work­ing site that is meant to com­pete with Facebook.

In any case, the search offered by a HAT could be a lot more accu­rate and cus­tomiz­able so that writ­ers can con­trol the results offered to users. Who knows? Maybe one day we could make it easy for users to rec­om­mend cer­tain top­ics, like the fea­tures found in Face­book and Google+.
