This paper examines a strategy for structuring one type of domain knowledge for use in extrapolation. It does so by representing information about causality and using this domain knowledge to select and combine forecasts. We use five categories to express causal impacts upon trends: growth, decay, supporting, opposing, and regressing. An identification of causal forces aided in the determination of weights for combining extrapolation forecasts. These weights improved average ex ante forecast… 
Decomposition by Causal Forces: An Application to Forecasting Highway Deaths
TLDR
Three conditions are hypothesized to be important for effectively decomposing a time series by causal forces: the forecaster has domain knowledge that can be applied directly to the target series, the domain knowledge can be used to structure the problem so that individual causal forces can be specified for one or more component series, and it is possible to obtain relatively accurate forecasts for each component.
Identification of Asymmetric Prediction Intervals Through Causal Forces
When causal forces are specified, the expected direction of the trend can be compared with the trend based on extrapolation. Series in which the expected trend conflicts with the extrapolated trend
Integration of Statistical Methods and Judgment for Time Series Forecasting: Principles from Empirical Research
TLDR
This literature suggests that integration generally improves accuracy when the experts have domain knowledge and when significant trends are involved, and when good domain knowledge is available for the future as well as for the past.
DEMAND FORECASTING: EVIDENCE-BASED METHODS Forthcoming in the Oxford Handbook in Managerial Economics
We reviewed the evidence-based literature related to the relative accuracy of alternative methods for forecasting demand. The findings yield conclusions that differ substantially from current
Rule-Based Forecasting: Using Judgment in Time-Series Extrapolation
TLDR
Rule-Based Forecasting (RBF) is an expert system that uses judgment to develop and apply rules for combining extrapolations that improved the selection of forecasting methods, the structuring of time series, and the assessment of prediction intervals.
Demand Forecasting: Evidence-Based Methods
We looked at evidence from comparative empirical studies to identify methods that can be useful for predicting demand in various situations and to warn against methods that should not be used. In

TLDR
Forecasts generated by five popular extrapolations are compared with each other and with a random-walk model over nearly 1500 situations and found to be successful on nondurable goods and series that historically have exhibited stable patterns.
