Title: Information Overload and National Culture: Assessing Hofstede


1
Information Overload and National
CultureAssessing Hofstedes Model Based on Data
from Two Countries
  • Ned Kock, Ph.D.
  • Dept. of MIS and Decision Science
  • Texas AM International University

2
Information overload
  • Situation characterized by an individual having
    more information to handle, in order to carry out
    one or more activities of a business process,
    than allowed by his or her (cognitive, time,
    technology etc.) resources.

3
Scores and ranks for the US and NZ - cultural
dimensions in Hofstedes model
4
Hofstedes country and region clusters framework
  • There is similarity in the scores, and
    particularly closeness in the ranks, for the US
    and New Zealand on each of the five cultural
    dimensions.
  • This similarity in the scores and ranks is
    reflected in Hofstedes (2001, p. 62) country and
    region clusters framework. The US and New Zealand
    are part of the same cluster, namely cluster 8,
    which also includes the following countries
    Australia, Canada, Great Britain, and Ireland.

5
Research questions
  • RQ1 Is information overload a relevant
    phenomenon from a business perspective?
  • RQ2 Does perceived information overload vary
    significantly between the US and New Zealand?
  • RQ3 Is the variation in perceived information
    overload consistent with predictions based on
    Hofstedes cultural dimensions?

6
Data collection
  • Perceptual and demographic data were collected
    from a sample of 108 MBA students.
  • Of those students, 59 were from a large
    university in Northeastern US, and 49 from a
    midsized university in New Zealand.
  • Nearly all students held professional or
    management positions at the time the data were
    collected.

7
Data analysis
  • The data were analyzed through a variety of
    methods, with the goal of answering each of the
    research questions.
  • Those methods include summarization of
    percentages, comparisons of means, structural
    equation modeling, and spreadsheet-based
    simulations.
  • For the comparisons of means, both parametric (t)
    and nonparametric (Mann-Whitney U) tests were
    employed.
  • For structural equation modeling, the partial
    least squares (PLS) technique was employed (Chin,
    1998 2001 Chin et al., 1996).

RQ3 Is the variation in perceived IO consistent
with Hofstedes model?
  • The distribution of scores provided by Hofstede
    (2001, p. 500) for the power distance dimension
    suggests a mean of 56.83 and a standard deviation
    of 21.81.
  • Therefore, the difference in power distance
    scores of 18 between the US and New Zealand is
    close to a full standard deviation.
  • The issue turns to whether the difference in
    power distance between the US and New Zealand
    could account for the significant country effects
    on perceived information overload and related
    predictors, particularly those observed in the
    PLS analysis.

15
RQ3 Is the variation in perceived IO consistent
with Hofstedes model?
  • A spreadsheet simulation was conducted to verify
    whether the difference in power distance between
    the US and New Zealand could explain the
    significant country effects on perceived
    information overload and related predictors.
  • The simulation presumed a relatively strong
    bivariate correlation of .575 between scores
    ranging from 1 to 100 (which is the approximate
    range of power distance scores in Hofstedes
    model), and perceived information overload. Such
    a correlation would account for the .179
    bivariate correlation between the variables
    country and perceived information overload.
  • The results of that simulation suggest that even
    a difference in scores of 18 would be enough to
    produce a difference between two perceived
    information overload means that would be
    significant at the p lt .05 level.

16
Conclusion
Final slide
  • If power distance were a strong predictor of
    information overload (something that cannot be
    strongly ascertained based on this study), the
    difference in power distance scores between the
    US and New Zealand could be large enough to
    explain the difference in the mean perceived
    information overload scores, and likely also the
    country effects suggested by the PLS analysis.
  • However, if this were the case, it would call
    into question the inclusion of the US and New
    Zealand in the same country cluster, since those
    two countries would appear to differ
    substantially in terms of power distance, and
    certainly in perceived information overload,
    which in turn appear to be relevant variables
    from a business perspective.
