According to the Myers-Briggs personality test developed by Carl Jung the ISTP is an introvert who senses over using intuition, thinks instead of feels and uses perception over judgement. This combination makes ISTPs excellent at analyzing a situation and swiftly correcting something. They are naturally quiet people who focus their energies on how things work. They tend to be a bit disorganized to outsiders but have order in their own chaos. The ISTP is best suited to be engineers, mechanics, anything involving technical skills or anything they can work one alone.
Approximately 5% of the population is ISTP of which 23% are women and 77% are men. This is personality type is quite uncommon in women. Amelia Earhart was an ISTP. She literally flew in the face of convention and did her own technical thing. In recent years, women have been more comfortable in taking roles that were once thought of as male ISTP positions like fire fighters, mechanics, surgeons and police officers.
Women still face the problem of scorn and disdain by men, especially fellow ISTPs for occupying these traditional roles. The scorn received makes the ISTP woman doubt herself and question if she is normal for being in that line of work or if something is wrong with her. Unlike her male counterpart she needs reassurance that her gender or femininity is at risk occupying these gender busting roles.
A job is genderless in the mind of a female ISTP and they feel the same allure as male ISTPs to the thrill and immediate satisfaction to the job or circumstance. Traditionally these types of women were the crafters or artisans of a community. ISTP men were also crafters but took more traditional roles such as blacksmith.
The ISTP woman spends more time thinking about her role in life than an ISTP man does not at the base of the personality but for the enormous uphill struggle with gender stereotypes. The two sexes both want the thrill, to fix things, are quiet by nature but a woman has more social pressure in pursuing her natural personality than a man. She often finds herself having to ignore her own personal style to fit into the mold of her role. She will dress more androgynously to fit the perceived social standards of a male role.
All in all there are not many differences between a male and female ISTP personality. The difficulty in the genders is for women who battle constant and current social stigma for occupying what is considered traditional male roles in society.
