In general, it takes about 30 seconds to form a good first impression. During this brief period, people often make judgments based on initial visual cues, body language, and demeanor. These initial impressions can have a significant impact on how individuals are perceived.
However, it's essential to note that first impressions can be influenced by various factors such as context, personal biases, and cultural differences. While the 30-second timeframe is a general guideline, forming a lasting and accurate impression may require more time and interaction.
Therefore, while the initial impression may take around 30 seconds, developing a deeper understanding of someone may take longer, potentially ranging from a few hours to several days depending on the complexity of the situation and the depth of the relationship.
