Writing with a pen like the inq pen can indeed help improve memory retention. Research has shown that handwriting engages more areas of the brain linked to visual processing and motor skills, which can enhance memory and understanding. For example, studies from Princeton University and UCLA have demonstrated that students who take handwritten notes retain more information and perform better, particularly when critical thinking is involved. This is because handwriting requires deeper mental processing compared to typing, which often leads to verbatim transcription and less cognitive effort.

Additionally, the act of writing by hand creates a tactile connection to the information, helping to cement it in your mind through motor memory. This multisensory experience can make the learning process more meaningful and effective.

So, while the exact percentage of improvement may vary, there is strong evidence to suggest that writing with a pen can significantly enhance memory retention and understanding.
