There’s a certain time of day that you’re more likely to lie, and it’s not when you first wake up in the morning. Recent research shows that people fibbed more in the afternoon, when offered a reward for being untruthful. The idea is that everyone has a certain reserve of will power. As the day goes on, it becomes depleted as we use bits of it up resisting that doughnut for breakfast or not buying that expensive sweater. When you’re tired, you lose your will power to be truthful, and take the easy way out. If its easier to tell a lie, when it’s afternoon, you’ll definitely be more likely to do it.
