In my opinion for a doctoral student in science and engineering the most important intelligence is mathematical logic intelligence which includes rational thinking and mathematical reasoning ability a

Furthermore, logical mathematical intelligence is not limited to the field of science and engineering. It is a valuable skill in many other areas, such as finance, economics, computer science, and even law. The ability to think logically and solve problems is highly valued by employers in these fields. Therefore, doctoral students with strong logical mathematical intelligence have a competitive advantage in the job market.

In conclusion, while there are many types of intelligence that are important for success in life, I believe that logical mathematical intelligence is the most important for doctoral students in science and engineering. This intelligence enables them to analyze data, develop and test theories, and solve complex problems, which are essential skills for scientific research. Additionally, logical mathematical intelligence is a valuable skill in many other fields, making it a highly sought-after skill in the job market.
