s ▁group ▁t ies ▁are ▁strong . ▁▁ ▁When ▁t ies ▁are ▁weak , ▁groups ▁prefer ▁a ▁stronger ▁leader ▁with ▁a ▁co er ci ve ▁power ▁base . ▁The ▁question ▁remains ▁whether ▁authorities ▁can ▁be ▁trust ed ▁in ▁gover ning ▁social ▁d ile mm as ▁and ▁field ▁research ▁shows ▁that ▁legit im acy ▁and ▁fair ▁procedures ▁are ▁extremely ▁important ▁in ▁citiz en ' s ▁willing ness ▁to ▁accept ▁authorities . ▁Other ▁research ▁emphas izes ▁a ▁greater ▁motiv ation ▁for ▁groups ▁to ▁successfully ▁self - organ ize , ▁without ▁the ▁need ▁for ▁an ▁external ▁authority ▁base , ▁when ▁they ▁do ▁place ▁a ▁high ▁value ▁on ▁the ▁resources ▁in ▁question ▁but , ▁again , ▁before ▁the ▁resources ▁are ▁sever ely ▁over har v ested . ▁An ▁external ▁" author ity " ▁is ▁not ▁pres umed ▁to ▁be ▁the ▁solution ▁in ▁these ▁cases , ▁however ▁effective ▁self - organ ization ▁and ▁collect ive ▁govern ance ▁and ▁care ▁for ▁the ▁resource ▁base ▁is . ▁ ▁Another ▁struct ural ▁solution ▁is ▁reducing ▁group ▁size . ▁Co operation ▁generally ▁decl ines ▁when ▁group ▁size ▁increases . ▁In ▁larger ▁groups ▁people ▁often ▁feel ▁less ▁responsible ▁for ▁the ▁common ▁good ▁and ▁believe , ▁right ly ▁or ▁wrong ly , ▁that ▁their ▁contribution ▁does ▁not ▁matter . ▁Red uc ing ▁the ▁scale — for ▁example ▁through ▁div iding ▁a ▁large ▁scale ▁d ile m ma ▁into ▁smaller ▁more ▁manage able ▁parts — m ight ▁be ▁an ▁effective ▁tool ▁in ▁raising ▁co operation . ▁Add itional ▁research ▁on ▁govern ance ▁shows ▁that ▁group
