The results of this study support our hypothesis that language can affect purchasing behavior. The use of the English language for the brand’s logo and slogan was found to increase satisfaction with the tea taste and brand identity, leading to an increase in the amount of goods purchased. This supports previous research on the impact of cognitive biases and the halo effect in shaping consumer perception and preferences.

It is important to note that these results are specific to the particular context and sample of this study, and further research is needed to explore the generalizability of these findings to other products, languages, and cultures. Additionally, it may be useful to consider other factors that may influence purchasing behavior, such as product price, availability, and quality.

Overall, this study provides valuable insights into the impact of language on consumer behavior, and highlights the importance of considering the role of language in shaping brand identity and affecting purchasing decisions. These findings can inform marketing strategies and help businesses better understand how to effectively communicate with their customers.

Additionally, the number of purchased goods also increased in comparison to the Persian logo and slogan condition. These results align with Boaz Keysar’s research, where he found that using a foreign language reduces decision-making biases, increasing the acceptance of both hypothetical and real bets with positive expected value. The study also supports our previous experiments in Ofogh-e-Kurosh Chain Stores and Hosseini Brothers’ website, where we found that using Persian numbers reduced purchasing behavior.

In conclusion, language plays a crucial role in shaping individuals’ purchasing behavior and brand satisfaction. Further research is necessary to better understand the impact of different languages on decision-making and consumer behavior. We encourage readers to see our previous experiments in Ofogh-e-Kurosh Chain Stores and Hosseini Brothers’ website, which demonstrate the influence of numerical notations and language on purchasing behavior.
