The Real Reason Why Some People Always Late
"If we have a lot of experience performing a task, we are more likely to underestimate how long it will take," Emily Waldum an adjunct professor at Campbell University in North Carolina and the lead author of a 2016 study published in the Journal of Experimental Psychology: General said.
In the study, Waldum found that environmental factors, such as music, can distort your sense of time.
Specifically, she showed that when doing a general knowledge questions task, some people incorrectly estimated the task's length based on the number of songs they heard playing in the background.
Younger adults tended to inflate their time estimates if they heard four short songs compared with two longer songs, something that didn't seem to influence older adults' perception of time.
In a 2022 study in the journal Virtual Reality, researchers asked participants to estimate the length of more or less crowded simulated subway trips. They found that crowded commutes felt like they took 10% longer than less busy rides, which was linked to it being an unpleasant experience.
Personality also plays a role in running late. Certain personality traits, such as reduced conscientiousness, can cause some people to forget tasks that they had planned ahead of time, Waldum said.
"Another factor that may influence a person's timeliness is how prone to multitasking they are," she added.
Research published in the journal Advances in Cognitive Psychology has shown that people juggling several tasks at once are less likely to remember and complete other scheduled tasks on time.
"The best-laid plans can fail simply because we don't have enough attentional resources left to carry them out successfully," Waldum informed.
