Significant proportions of  African-American (30%) and Hispanic (39%) adults say they are more  likely to support a cause or social issue online than offline, according  to the results of a new
study by Georgetown University's  Center for Social Impact Communication and Ogilvy Public Relations  Worldwide. That compares to 24% of white American adults agreeing with  the same
statement.
The higher rate of online  engagement reflects a greater belief in social media's capacity for  spreading awareness about social issues and causes. 58% of  African-Americans
and 51% of Hispanics surveyed by Georgetown and Ogilvy  said social networks are effective means for getting the word out about  important issues, compared to just 34% of Caucasians. In keeping with
this attitude, African-Americans and Hispanics are also more likely than  Caucasians to turn to social media for additional information about  issues and causes that matter to them (31% and 27%,
compared to 21%,  respectively).
By the same token there is some  skepticism about online activism, echoing Malcolm Gladwell's critique  -- namely, that social media makes it easy to
express support for causes  in a hollow, superficial way which doesn't ultimately translate into  real action. 
On that note, a good number of  Hispanics believe that people
"like" causes on Facebook without really  caring about them, and a large proportion of all three groups said they  feel that email about social causes sometimes feels like SPAM (76% of
Caucasians, 69% of Hispanics, and 66% of African-Americans). 48% of  Caucasians and 51% of Hispanics also say they get too many emails about  causes, compared to 33% of African-Americans.
