Why do democracies align more with U.S. positions in important UN General Assembly votes?

The core puzzle in CarterandStone2012 is straightforward: democracies are observed to support U.S. positions in important UN General Assembly (UNGA) votes more often than non-democracies. The article asks whether this pattern reflects genuine agreement with the United States or influence through aid-based pressure and inducements.

Main research question

The article’s main research question is:

• Why are democracies more supportive of U.S. positions in important UNGA votes than non-democracies?

As the abstract of CarterandStone2012 explains, this relationship could arise because democracies share U.S. views, or because U.S. influence attempts tied to foreign aid affect their voting. Since U.S. law after 1985 required the State Department to identify “important” votes and link aid disbursements to voting behavior, the authors argue that coercion or inducement is a plausible part of the story, not just shared values.

The three proposed explanations

CarterandStone2012 identifies three competing explanations for why democracies align more with the United States on important UNGA votes.

1. Shared preferences

This explanation says democracies vote with the United States because they sincerely agree with it more often. In this view, democracies have similar values, worldviews, or foreign-policy goals. The article links this idea to broader arguments that democracies often cooperate with one another, settle disputes peacefully, and form alliances more readily with fellow democracies.

Under this explanation:

• Democracies support U.S. positions because their preferences are naturally closer to U.S. preferences.
• Any connection between aid and voting could be incidental, because the United States may also prefer to give aid to democracies.
• The voting alignment is mainly about agreement, not pressure.

2. Greater vulnerability to influence

This explanation says democracies may be more susceptible to U.S. influence attempts than autocracies. Here the key idea is not that democracies necessarily agree more with the United States, but that they are more likely to change or shape their voting because rewards or punishments matter more to them.

Under this explanation:

• Democracies are more responsive when the United States uses aid as leverage.
• Their higher alignment comes from being more vulnerable to pressure or inducements.
• The focus is on how the target country reacts to influence attempts.

The article contrasts this with an argument that autocrats might actually be easier to buy because they can more freely trade policy concessions. That contrast helps clarify the question the authors are testing: which regime type is really more affected by U.S. leverage?

3. More credible influence attempts

This explanation says democracies align more with the United States because U.S. threats and promises are more credible when directed at democracies. In other words, democracies may expect that if they cooperate, the United States really will reward them, and if they defect, it really will punish them.

Under this explanation:

• The key issue is not the target’s underlying preferences.
• The key issue is also not simply vulnerability alone.
• Instead, democracies are more likely to believe U.S. rewards and punishments will actually be carried out.

According to 10.1.1.727.6480, the authors argue that it is more politically acceptable for the United States to reward democracies with aid, and therefore such inducements are more believable. The same logic applies to punishments: U.S. aid linkage is more credible with democracies than with autocracies.

How the explanations differ

A useful way to distinguish the three explanations is to ask three different questions:

• Shared preferences: Do democracies vote with the United States because they already want the same outcomes?
• Greater vulnerability: Do democracies vote with the United States because they are more affected by U.S. pressure or incentives?
• More credible influence attempts: Do democracies vote with the United States because U.S. threats and promises are more believable when aimed at them?

What the article says about the puzzle

The evidence reported in CarterandStone2012 rejects the shared-preferences explanation. The authors conclude that democracies’ preferences are not inherently more pro-U.S.; in fact, they describe democracies’ underlying preferences as more oppositional than those of authoritarian governments. Yet democracies still vote more often with the United States because they are more likely to face credible rewards and punishments tied to aid.

Both CarterandStone2012 and 10.1.1.727.6480 emphasize that democracies are more likely than autocracies to be punished for non-cooperation and rewarded for cooperation. That makes U.S. influence attempts more credible in democratic cases, helping explain why democratic alignment is higher on important UNGA votes.

Key takeaway

• The article’s main question is why democracies support U.S. positions more often in important UNGA votes.
• It tests three explanations: shared preferences, greater vulnerability to influence, and more credible influence attempts.
• The article concludes that the pattern is not mainly due to shared preferences.
• Instead, democratic alignment is better explained by the credibility of U.S. rewards and punishments, and related strategic influence through aid.
