It is a common charge that excessive television viewing drives down rates of civic and social involvement. A recent study by Benjamin A. Olken, an economist at MIT, shows just how true that is, measuring how much people’s community participation decreases for every channel they receive.

Indonesia boasts a strong tradition of community involvement. A typical village has a broad range of civic activities, including religious study groups, women’s organi­zations, savings and credit partnerships, and neighborhood assoc­iations. In Olken’s study of 600 villages in east and central ­Java—­one of the most densely populated places on ­earth—­the average community had nearly 180 different groups. But that number dropped precipi­tously in areas with better television and radio reception. With just one more TV station available than average, the number of com­mun­ity organizations dropped by about ­12.

There are 11 major stations broadcasting throughout Indonesia (up from just one, the govern­ment-owned TVRI, in 1993), but the average household in Olken’s study received only five. The Indonesians in his survey spent 123 minutes watching TV and 60 minutes listening to the radio each day. When a sixth channel was available, household viewing increased by 14 minutes a day and attendance at meetings fell by 11 percent.

Over a ­three-­month period, the extra time in front of the tube correlated with participation in four percent fewer social activities.

The decline in participation was more pronounced among organizations dedicated to improving local infrastructure, school committees, neighborhood associations, and savings and credit partnerships. Religious groups, which made up about ­one-­fifth of the groups but drew about 40 percent of the attendance of all groups combined, didn’t see their numbers drop quite as steeply as the secular groups. Richer respondents with more TV channels reduced their participation in social groups more than other ­demographics.

Interestingly, the decline in the quantity of civic participation was not matched by a decline in the quality of the civics. Some of the meetings Olken examined were related to a massive ­road-­building project financed by the World Bank. Although atten­dance was lower in areas with greater TV reception, just as many people were likely to speak, and they discussed the same number of problems. Of course, Olken points out, these small meetings about local roads didn’t receive much media attention. But for higher levels of govern­ment, increased TV reception means more time in the public ­eye—­which might have a greater impact than additional meeting ­attendees.
