It is based on field research data collection, transverse regarding time span and oriented to correlation relationships between variables. The survey was conducted in a sample of 201 professionals working in organizations located at the city of S??o Paulo, Brazil and performing jobs in which strategic decisions are taken. Questionnaires included respondents demographic data, their perceptions about environmental business uncertainty, the existence of stress related to strategic decision taking as well as their personal style of decision making. Results confirmed different degrees of perceived uncertainty on the business environment and revealed six different styles of decision-making and positive associations between: (1) demographic variables such as age, time of professional experience and hierarchical level of the job with the decision-making style adopted; (2) the stress sensation with the perception of uncertainty of State and of Response and (3) the stress sensation with the study operational hypothesis called adjustment (fit). This research fosters the understanding of how the perceived environmental uncertainty affects the strategic decision-making process and helps to identify possible stress sources for the strategic decision maker. It also confirms the role played by age and professional experience in adopting more flexible patterns in decision making such as intuition and reaffirms the point of view of authors who consider stereotyped the statement that: women is the naturally intuitive gender. Finally, it points out as future research the need to explore new ways that can provide a better fit between individual profiles and the degree of environmental uncertainty on the business environment faced by organizations. / O presente estudo avalia a utiliza????o da raz??o e da intui????o no processo decis??rio em estrat??gia, dada certa percep????o de incerteza no ambiente de neg??cios. Baseia-se em uma pesquisa descritiva, com dados prim??rios, de rela????o temporal transversal e delineamento correlacional. O m??todo utilizado foi o de survey , atrav??s da constru????o de dois instrumentos de pesquisa in??ditos, em uma amostra de 201 participantes, composta de profissionais que pertencem a n??veis hier??rquicos que tomam decis??es estrat??gicas nas organiza????es e cujas empresas em que trabalham possuem sede ou escrit??rios na cidade de S??o Paulo, Brasil. Os question??rios foram preparados para coletar dados demogr??ficos do respondente, sua percep????o de incerteza no ambiente de neg??cios, a presen??a de sensa????o de estresse ao tomar decis??es estrat??gicas e seu estilo de tomada de decis??o. Os resultados possibilitam identificar diferentes tipos de percep????o de incerteza, seis estilos decis??rios diferentes, al??m de associa????es entre: (1) vari??veis demogr??ficas tais como idade, tempo de experi??ncia profissional e n??vel hier??rquico com o estilo decis??rio adotado; (2) a sensa????o de estresse com a percep????o de incerteza de Estado e de Resposta e (3) a sensa????o de estresse com a hip??tese de trabalho denominada ajustamento. A elabora????o desta pesquisa contribui para a melhor compreens??o da influ??ncia da percep????o de incerteza quanto ao ambiente de neg??cios, no processo decis??rio em estrat??gia, e para detectar poss??veis fontes de estresse para os tomadores de decis??o. Tamb??m confirma a import??ncia da idade e da experi??ncia profissional na ado????o do estilo intuitivo e reafirma a posi????o de autores que consideram ser uma vis??o estereotipada a afirma????o que: o sexo feminino ?? naturalmente intuitivo. Em continuidade a esta linha de pesquisa, trabalhos futuros poder??o possibilitar novos passos na busca da efic??cia organizacional atrav??s da melhor adequa????o do perfil dos profissionais ao n??vel de incerteza no ambiente de neg??cios vivenciado pelas organiza????es.
