Why did the Trojans believe sinon and not Laocoon about the wooden horse?

The Trojans believed Sinon because he skillfully crafted a convincing story, portraying himself as a victim of the Greeks and claiming that the wooden horse was an offering to appease the gods. His emotional appeal and apparent sincerity won over the Trojans, especially since they were eager to believe in a sign of victory. In contrast, Laocoon's warning about the horse was met with skepticism, as the Trojans dismissed him as a misanthrope and were influenced by their desire to celebrate their supposed victory over the Greeks. Ultimately, their trust in Sinon’s narrative overshadowed Laocoon's caution.
